manual: patches are not applied for SITE_METHOD = local

We had several remarks on the mailing list of users that were surprised
that patches were not applied for packages whose SITE_METHOD is local.
So document this.

Note that for OVERRIDE_SRCDIR itself it is already documented:

  When Buildroot finds that for a given package, an
  <pkg>_OVERRIDE_SRCDIR has been defined, it will no longer attempt to
  download, extract and patch the package. Instead, it will directly use
  the source code available in in the specified directory.

arch/xtensa: allow specifying path to tarball file

currently, specifying a custom Xtrensa core is done with two variables:
  - the core name
  - the directory containing the overlay tarball

However, the core name only serves to construct the tarball name, and is
not used whatsoever to configure any of the toolchain components
(binutils, gcc or gdb), except through the files that are overlayed in
their respective source trees.

This has two main drawbacks:
  - the overlay file must be named after the core,
  - the tarball can not be compressed.

Furthermore, it also makes it extremely complex to implement a download
of that tarball.

So, those two variables can be squeezed into a single variable, that is
the complete path of the overlay tarball.

Update the qemu-xtensa defconfig accordingly.

Note: we do not add a legacy entry for BR2_XTENSA_CORE_NAME, since it
was previously a blind option in the last release, and there's been no
release since we removed BR2_XTENSA_CUSTOM_NAME. So, we just update the
legacy comments for BR2_XTENSA_CUSTOM_NAME, since that's all the user
could have seen in any of our releases so far.

So, when building the host variant of execline, this path will be used in the
target service scripts generated by the host variant of `s6-rc-compile`. If not

mtd: host variant needs host-util-linux, host-e2fsprogs

Since mtd was converted to the package infrastructure in commit
de4cf4e9135e198d4c3beefc8ad63c03870eb78a ("mtd: convert to gentargets,
add host package"), its host variant depended on host-e2fsprogs. At
the time, only a host variant of the mtd package was available.

When a target variant of mtd was introduced in commit
b50e0fa113bf641a3764ae99b94bb7ba4e1e8f85 ("mtd: add option to build
mkfs.ubifs for target"), it depended on util-linux.

So today, the target variant continues to depend on util-linux, while
the host variant depends on e2fsprogs. What mkfs.ubifs really needs
is libuuid, which is provided by util-linux. It was in fact provided
by the fact that host-e2fsprogs depends on host-util-linux.

But really, host-e2fsprogs is not needed as a dependency, so use
host-util-linux to be consistent with the target variant.

toolchain: replace absolute symlinks by relative symlinks during sysroot copy

In commit 32bec8ee2fb00c6750fa842bbb0eb79b0c081fa2
("toolchain-external: copy ld*.so* for all C libraries") we changed
how the musl dynamic linker symbolic link was being created. Instead
of having specific logic in Buildroot, we switched to simply copying
the ld*.so.* symbolic link from staging to target, as well as the
target of this symbolic link.

However, it turns out that by default, musl creates its dynamic linker
symbolic link with an absolute path as the target of the link:
/lib/libc.so.

Therefore, external Musl toolchains built with Buildroot look like
this:

  lrwxrwxrwx 1 thomas thomas      12 Jul  4 19:46 ld-musl-armhf.so.1 -> /lib/libc.so

The principle of the copy_toolchain_lib_root function, which is used
to copy libraries from staging to target, is to copy symbolic links
and follow their targets. In this case, it means we end up copying
/lib/libc.so (from the host machine) into the target folder. From
there on, there are two cases:

 1. /lib/libc.so exists in your host system. It gets copied to the
    target. But later on, Buildroot also copies /lib/libc.so from
    staging to target, overwriting the bogus libc.so. So everything
    works fine, even though it's admittedly ugly.

 2. /lib/libc.so doesn't exist in your host system. In this case, the
    build fails with no clear error message.

This problem does not happen with Musl toolchains built by
Crosstool-NG, because Crosstool-NG replaces the absolute target of the
dynamic linker symbolic link by a relative path.

However, since we want to support existing Buildroot Musl toolchains
and generally work with the fact that Musl by default installs an
absolute symlink, the following commit improves the
copy_toolchain_sysroot function to replace symbolic links with an
absolute destination to use a relative destination. I.e, in staging,
the ld-musl-armhf.so.1 symbolic link looks like this:

lrwxrwxrwx 1 thomas thomas 14 Jul  5 22:59 output/staging/lib/ld-musl-armhf.so.1 -> ../lib/libc.so

xvisor: fix build on AArch64

Xvisor was failing to build on AArch64 with:

package/xvisor/xvisor.mk:60: *** No Xvisor defconfig name specified, check your BR2_PACKAGE_XVISOR_DEFCONFIG setting.  Stop.

The first problem is that the Config.in file had a typo: it was using
BR2_AARCH64 instead of BR2_aarch64, and therefore the
BR2_PACKAGE_XVISOR_DEFCONFIG variable had no value.

Once this is fixed, another problem occurs: the ARCH variable needs to
be specified as "arm" for XVisor, for both ARM and AArch64. Therefore,
a XVISOR_ARCH variable is introduced, which is calculated according to
the Buildroot configuration options. Only x86-64, arm and aarch64 are
supported by Xvisor currently, so it remains simple.

toolchain/helpers.mk: fix creation of DESTDIR in copy_toolchain_lib_root

In commit b3cc7e65ee, the definition of the DESTDIR variable was moved
down into the loop that follows symlinks in the libraries that are
copied to target. However, the corresponding mkdir was not moved down,
so that no directories are ever created.

In practice, this mkdir is normally redundant since the directories
should already have been created as part of creating STAGING_DIR.
Still, the current situation is clearly wrong, so fix it by moving the
mkdir down to after the assignment to DESTDIR.

While we're at it, also remove a redundant empty line. It's a leftover
from when a lot of variables were declared above.

if this should be /bin or /usr/bin or $(HOST_DIR)/bin. Looking at the

/usr/bin doesn't appear anywhere in the installed files.
