sysdeps/unix/make-syscalls.sh and sysdeps/unix/Makefile use GNU Bash's
${parameter/pattern/string} parameter expansion. Non-Bash shells (e.g.
dash or BusyBox ash when built with CONFIG_ASH_BASH_COMPAT disabled)
don't support this expansion syntax. So glibc will fail to build when
$(SHELL) expands to a path that isn't provided by Bash.
An example build failure:
for dir in [...]; do \
test -f $dir/syscalls.list && \
{ sysdirs='[...]' \
asm_CPP='gcc -c -I[...] -D_LIBC_REENTRANT -include include/libc-symbols.h -DASSEMBLER -g -Wa,--noexecstack -E -x assembler-with-cpp' \
/bin/sh sysdeps/unix/make-syscalls.sh $dir || exit 1; }; \
test $dir = sysdeps/unix && break; \
done > [build-dir]/sysd-syscallsT
sysdeps/unix/make-syscalls.sh: line 273: syntax error: bad substitution
This patch simply replaces the three instances of the Bash-only syntax
in these files with an echo and sed command substitution.

strcoll is implemented using a cache for indices and weights of
collation sequences in the strings so that subsequent passes do not
have to search through collation data again. For very large string
inputs, the cache size computation could overflow. In such a case,
use the fallback function that does not cache indices and weights of
collation sequences.
Fixes CVE-2012-4412.
strcoll currently falls back to alloca if malloc fails, resulting in a
possible stack overflow. This patch implements sequence traversal and
comparison without caching indices and rules.
Fixes CVE-2012-4424.
Statically built binaries use __pointer_chk_guard_local,
while dynamically built binaries use __pointer_chk_guard.
Provide the right definition depending on the test case
we are building.
The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.
