usb_modeswitch_data: requires thread support

usb_modeswitch_data unconditionally selects usb_modeswitch, but
usb_modeswitch depends on thread support. This commit has the thread

libglib2: needs threads

This commit adds a dependency of the libglib2 package on thread
support in the toolchain, since upstream libglib2 doesn't build
without thread support. The commit is rather large as it involves
propagating the dependency on thread support to all reverse
dependencies of the libglib2 package.

uclibc: uclibc-menuconfig: don't depend on gcc/binutils

With the move of uclibc to package/uclibc, the uclibc-menuconfig target now
depends on uclibc-configure, which brings in the build of
binutils/gcc-initial/mpfr/gmp, causing it to take ages with a clean tree.

Fix it by moving the basic .config mangling to the patch step, and depend
on that for menuconfig instead.

Notice that this is broken for _OVERRIDE_SRCDIR users, just like for
busybox, but as that is presumably a small subset of the buildroot
user base (and these advanced users can just run menuconfig in their
local uClibc tree), so this is considered the lesser evil of the two.

this.

toolchain: check ARM EABI vs. EABIhf for external toolchains

Following the introduction of the support of EABIhf as a second ARM
ABI, it is important to check whether the external toolchain provided
by the user actually uses the ABI that has been selected in the
Buildroot configuration. This commit introduces such a check by
looking at the 'Tag_ABI_VFP_args' tag of the architecture-specific
section of the ELF headers. This assumes that ELF is the binary format
used on ARM, which may not be the case on ARM noMMU systems (they use
the FLAT binary format), but Buildroot doesn't have support for such
systems at the moment.

Also ensure the correct CFLAGS are passed to the cross compiler for the
test, so the correct variant is used in case the toolchain is multilib.

uclibc: add Thumb2 fixes

This commit adds three patches to uClibc that are needed to make
Thumb2 support work properly:

 uclibc-0006-arm-clone-restore-stack-pointer-just-after-return-fr.patch
 uclibc-0007-arm-clone.S-Add-missing-IT-instruction-for-Thumb2.patch
 uclibc-0008-arm-move-check-for-BX-to-its-own-header.patch

The first one is a necessary dependency of the second one. Both of
those patches have already been merged upstream, after 0.9.33.2. The
third one hasn't been merged upstream yet, but it has already been
submitted a while ago by Yann E. Morin, without receiving attention
from upstream.

arch/arm: add support for Thumb2

Until now, we were using the default ARM instruction set, as used by
the toolchain: the 32 bits ARM instruction set for the internal
backend, and for external toolchain, whatever default was chosen when
the toolchain was generated.

This commit adds support for the Thumb2 instruction set. To do so, it:

 * provides a menuconfig choice between ARM and Thumb2. The choice is
   only shown when Thumb2 is supported, i.e on ARMv7-A CPUs.

 * passes the --with-mode={arm,thumb} option when building gcc in the
   internal backend. This tells the compiler which type of
   instructions it should generate.

 * passes the m{arm,thumb} option in the external toolchain
   wrapper. ARM and Thumb2 code can freely be mixed together, so the
   fact that the C library has been built either ARM or Thumb2 and
   that the rest of the code is built Thumb2 or ARM is not a problem.

toolchain-external: update config options after EABIhf introduction

The introduction of the EABIhf ABI requires a few updates to the
configuration options for external toolchains, in order to ensure that
the user doesn't do any invalid selection. In detail:

 * The Linaro ARM toolchains now depend on BR2_ARM_EABIHF, because
   that's the ABI they use, and it is incompatible with EABI. The
   comment about the availability of Linaro toolchains is updated to
   inform users selecting EABI that they should select EABIhf if they
   want to see Linaro toolchains.

 * The Sourcery CodeBench toolchains now depend on BR2_ARM_EABI,
   because that's the ABI they use. A comment is added to inform users
   that have selected EABIhf that Sourcery CodeBench are only
   available when EABI is used.

 * The Arago toolchains now depend on BR2_ARM_EABI, because that's the
   ABI they use. The description of the ARMv7 Arago toolchain is also
   slightly improved.

arch: improve ARM floating point support and add support for EABIhf

This commit introduces the support for the EABIhf ABI, next to the
existing support we have for EABI and OABI (even though OABI support
is deprecated). EABIhf allows to improve performance of floating point
workload by using floating point registers to transfer floating point
arguments when calling functions, instead of using integer registers
to do, as is done in the 'softfp' floating point model of EABI.

In addition to this, this commit introduces a list of options for the
floating point support:
 * Software floating point
 * VFP
 * VFPv3
 * VFPv3-D16
 * VFPv4
 * VFPv4-D16

and it introduces some logic to make sure the options are only visible
when it makes sense, depending on the ARM core being selected. This is
however made complicated by the fact that certain VFP capabilities are
mandatory on some cores, but optional on some other cores. The kconfig
logic tries to achieve the following goals:

 * Hide options that are definitely not possible.

 * Use safe default values (i.e for Cortex-A5 and A7, the presence of
   the VFPv4 unit is optional, so we default on software floating
   point on these cores)..

 * Show the available possibilities, even if some of them are not
   necessarily working on a particular core (again, for the Cortex-A5
   and A7 cores, there is no way of knowing whether the particular
   variant used by the user has VFPv4 or not, so we select software
   floating point by default, but still show VFP/VFPv3/VFPv4 options).

It is worth noting that this commit doesn't add support for all
possible -mfpu= values on ARM. We haven't added support for fpa, fpe2,
fpe3, maverick (those four are only used on very old ARM cores), for
vfpv3-fp16, vfpv3-d16-fp16, vfpv3xd, vfpv3xd-fp16, neon-fp16,
vfpv4-sp-d16. They can be added quite easily if needed thanks to the
new organization of the Config.in options.

arch: Refactor BR2_SOFT_FLOAT into per-architecture options

As we are going to introduced a more advanced support of floating
point options for the ARM architecture, we need to adjust how the
soft-float option is handled. We replace the current hidden option
BR2_PREFER_SOFT_FLOAT option and the visible BR2_SOFT_FLOAT option by:

 * A global hidden BR2_SOFT_FLOAT option, defined in arch/Config.in,
   that tells whether the architecture-specific code is using software
   emulated floating point. This hidden option can be used throughout
   Buildroot to determine whether soft float is used or not.

 * Per-architecture visible BR2_<arch>_SOFT_FLOAT options, for the
   architecture for which it makes sense, which allows users to select
   soft float emulation when needed.

This change will allow each architecture to have a different way of
presenting its floating point capabilities.

This commit has two additional options:
