ebx was recently added to the x86 inline asm MULADDC_STOP clobber list to
fix#1550, but this causes the build to fail with GCC < 5 when building in
PIC mode with errors like:
include/mbedtls/bn_mul.h:46:13: error: PIC register clobbered by ‘ebx’ in ‘asm’
This is because older GCC versions treated the x86 ebx register (which is
used for the GOT) as a fixed reserved register when building as PIC.
This is fixed by an improved register allocator in GCC 5+. From the release
notes:
Register allocation improvements: Reuse of the PIC hard register, instead of
using a fixed register, was implemented on x86/x86-64 targets. This
improves generated PIC code performance as more hard registers can be used.
https://www.gnu.org/software/gcc/gcc-5/changes.html
As a workaround, add a patch to detect this situation and disable the inline
assembly, similar to the MULADDC_CANNOT_USE_R7 logic.

brltty has a very inventive buildsystem, where it internall runs
./configure for the build machine In doing so, it generates a list
of make variables to define what the build machine supports, like
it does for the target.
However, the build variables are generated with a convoluted sed
script that scans the target list, and appends _FOR_BUILD to each
target variables. Then, both lists are included from the Makefile,
on the assumption that the build variables will not clash with the
target variables.
Where it gets interesting, is that that sed script considers the
variables names to match '[A-Za-z][A-Za-z0-9_]*'
And there we see why ATSPI2_PACKAGE does not match: it contains a
digit.
So, some build variables will inevitably override target ones.
Fix that by simply expanding the matching regexp to allow digits
in variable names.

The check_musl function currently builds a program and verifies if the
program interpreter starts with /lib/ld-musl. While this works fine
for dynamically linked programs, this obviously doesn't work for a
purely static musl toolchain such as [1].
There is no easy way to identify a toolchain as using the musl C
library. For glibc, dynamic linking is always supported, so we look at
the dynamic linker name. For uClibc, there is a distinctive
uClibc_config.h header file. There is no such distinctive feature in
musl.
We end up resorting to looking for the string MUSL_LOCPATH, which is
used by musl locale_map.c source file. This string has been present in
musl since 2014. It certainly isn't a very stable or convincing
solution to identify the C library as being musl, but it's the best we
could find.
Note that we are sure there is a libc.a file, because the
check_unusable_toolchain function checks that there is a such a file.

We sometimes create dangling symlinks in the target directory. That is
because we need canonical targets, as relative targets don't work well
with BR2_ROOTFS_MERGED_USR. For example, the vim package installs the
/bin/vi symlink to /usr/bin/vim. This symlink might be dangling when the
build host has no vim installed there.
Patch the busybox install.sh script to avoid clobber of dangling
symlinks.

Depending on the configuration, the cpp output may contain the string 'yes'
in a comment if built under a path containing 'yes', confusing the _AIX
test:
${CROSS}-cpp conftest.h

\# 31 "<command-line>"

\# 32 "<command-line>" 2
\# 1 "conftest.txt"
If misdetected, the configure script adds -lc128 to LIBS, causing the
AC_CHECKS_FUNCS check for stat64 to fail, which in turn causes compilation
errors about redefinition of symbols:
In file included from ./src/include/pv-internal.h:9:0,
from src/pv/file.c:5:
./src/include/config.h:76:18: error: redefinition of 'struct stat'
# define stat64 stat
^
Fix it by only matching on 'yes' on a line by itself.
As pv doesn't cleanly autoreconf (it doesn't use automake and configure.in
is located in subdir), instead directly patch configure.

ERROR: Incomplete download, or man-in-the-middle (MITM) attack
In the case of custom Linux kernel versions, this is fatal, because there isn't
necessarily a hash file to indicate that wget's empty tarball is wrong.
This seems to have been broken by commit c8ef0c03b0, because:
1. BR2_PRIMARY_SITE always appends "urlencode" (package/pkg-download.mk)
2. Anything with the "|urlencode" suffix in $uri will end up using wget due to
the backend case wildcarding.
3. The wget backend rejects file:/// URLs ("unsupported scheme"), and we end up
with an empty .tar.gz file in the downloads directory.
Fix that by shell-extracting the backend name from the left of "|". I'm not
positive if all URLs will have a "|", so this code only looks for a "|" left of
the "+".

MySQL detects on the build machine where the hostname program is
located, and uses this value in a number of configuration files and
scripts that are generated and installed in the target:
output/target$ grep -r "bin/hostname" *
etc/inittab:::sysinit:/bin/hostname -F /etc/hostname
usr/share/mysql/mysql.server: pid_file=$datadir/mysqlmanager-`/usr/bin/hostname`.pid
usr/share/mysql/mysql.server: server_pid_file=$datadir/`/usr/bin/hostname`.pid
usr/bin/mysql_install_db:hostname=`/usr/bin/hostname`
usr/bin/mysqld_safe: err_log=$DATADIR/`/usr/bin/hostname`.err
usr/bin/mysqld_safe: pid_file="$DATADIR/`/usr/bin/hostname`.pid"
However, the hostname on the build machine may not necessarily be at
the same location as the hostname program on the target. Buildroot has
its hostname program (coming from Busybox) in /bin, but some Linux
distributions (such as Fedora) use /usr/bin/hostname, causing the
incorrect hostname paths above.
This commit fixes that by passing the appropriate autoconf cache
variable value.
