uboot-tools: fix dynamic linking against OpenSSL

Commit 95f9a5c3df8e4226b99438efccf0bf21eecb573d fixed the static
linking issue of uboot-tools mkimage against OpenSSL, but in the
process broke the dynamic linking case. This commit adjusts the
uboot-tools patch to make sure both static and dynamic linking work.

An updated version of the patch has been submitted upstream.

binutils: fix xtensa ld bug triggered by --gc-sections

elf_xtensa_gc_sweep_hook doesn't correctly unreference symbols that were
made local, that results in link failure with the following message:

  BFD (GNU Binutils) 2.24 internal error, aborting at elf32-xtensa.c line
  3372 in elf_xtensa_finish_dynamic_sections

elf_xtensa_gc_sweep_hook determines symbol reference type (PLT or GOT) by
relocation type. Relocation types are not changed when symbol becomes
local, but its PLT references are added to GOT references and
plt.refcount is set to 0. Such symbol cannot be unreferences in the
elf_xtensa_gc_sweep_hook and its extra references make calculated GOT
relocations section size not match number of GOT relocations.

Fix it by treating PLT reference as GOT reference when plt.refcount is
not positive.

acl, attr: fix libdir variable in .la files

The acl and attr packages are using autoconf and libtool, but not
automake, which causes all sort of troubles. Some of them are already
worked around in acl.mk and attr.mk, but there is another one: the
libdir variable in the .la file remains empty, which causes libtool to
sometimes be confused about where the acl and attr libraries are
installed.

This was causing build issues with libarchive, but interestingly only
in situations where we had zlib *and* libxml2 also part of the build,
which maybe affects how libtool in libarchive behaves since libarchive
can use zlib and libxml2 as optional dependencies.

So what this patch does is to mungle the libattr.la and libacl.la
files to make sure they contain the right libdir values. Yocto is
doing exactly the same thing.

Upstream attr and acl have been converted fully to automake, so
hopefully the upcoming upstream release will allow us to get rid of
those hacks, but in the mean time, it seems to be the most appropriate
solution.

Here is a minimal defconfig that exhibits the problem, and which
allows to show that this patch fixes it:

BR2_bfin=y
BR2_BINFMT_FLAT=y

host-autoconf-archive: install to a non-standard location

The host-autoconf-archive package was added to provide the necessary
autoconf macros for the libsigrok package, and later also used for the
thrift package.

However, it installs its autoconf macro in
$(HOST_DIR)/usr/share/aclocal, which is part of the include directory
of autoconf macros used for all autoreconf invocations. Unfortunately,
using those macros for all packages is causing a number of
regressions: one on host-ola fixed in commit
884af65fd5ddc548f19a26162f905a32ef0b53b3, and one in snmpp. Those
packages are autoreconf'ed, but if they are autoreconf'ed with the
autoconf-archive macros installed, they no longer work.

To solve this problem, this commit implements a simple solution that
makes using host-autoconf-archive macros an opt-in mechanism. To
achieve this, the autoconf-archive package is modified to install its
macros in a special directory, and only the packages that really want
to use those macros will have to pass a -I flag pointing to this
directory in their <pkg>_AUTORECONF_OPTS variable.

lxc: mark as not available in BR2_STATIC_LIBS configs

Even though lxc uses the autotools, it does not use libtool to build
its libraries, and does it manually. It forces building a shared

toolchain/external: better report RPC error for custom toolchains

Currently, we instruct users to enable/disable BR2_TOOLCHAIN_HAS_NATIVE_RPC
but that is a blind option. The only option users can set/unset is
BR2_TOOLCHAIN_EXTERNAL_INET_RPC.

Use that in the error message.

Notes: the only way for this message to appear is for a custom external
toolchain, either downloaded or pre-installed, so even though we check
the validity of the toolchain with BR2_TOOLCHAIN_HAS_NATIVE_RPC, we do
report on BR2_TOOLCHAIN_EXTERNAL_INET_RPC.

ipmiutil: force md2 off

The configure test runs against LIB_DIR (which is --libdir in configure
parlay) hence it's against the distro openssl version.
On newish openssl versions md2 is disabled by default, and buildroot
doesn't try to enable it (it's obsolete), but if the distro
libcrypto/openssl has it enabled then ipmiutil tries to use it.

Force it off to avoid build breakage. Fixes:
