Adding BUILD_CC to the STAGE1 bootstrap recipes

glibc no longer installs files in /usr/lib/locale, so we don't need to
have hacks in place for it anymore.

+    Make __extern_always_inline usable on clang++ again
+    
+    The fix for BZ #17266 (884ddc5081278f488ef8cd49951f41cfdbb480ce)
+    removed changes that had gone into cdefs.h to make
+    __extern_always_inline usable with clang++.  This patch adds back
+    support for clang to detect if GNU inlining semantics are available,
+    this time without breaking the gcc use case.  The check put here is
+    based on the earlier patch and assertion[1] that checking if
+    __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ is defined is sufficient
+    to determine that clang++ suports GNU inlining semantics.
+    
+    Tested with a simple program that builds with __extern_always_inline
+    with the patch and fails compilation without it.

+Author: Carlos O'Donell <carlos@redhat.com>
+Date:   Wed Nov 19 11:44:12 2014 -0500
+
+    CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
+    
+    The function wordexp() fails to properly handle the WRDE_NOCMD
+    flag when processing arithmetic inputs in the form of "$((... ``))"
+    where "..." can be anything valid. The backticks in the arithmetic
+    epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+    command substitution. This allows an attacker to attempt to pass
+    dangerous commands via constructs of the above form, and bypass
+    the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+    in exec_comm(), the only place that can execute a shell. All other
+    checks for WRDE_NOCMD are superfluous and removed.
+    
+    We expand the testsuite and add 3 new regression tests of roughly
+    the same form but with a couple of nested levels.
+    
+    On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+    testing. If any forks are detected during the execution of a wordexp()
+    call with WRDE_NOCMD, the test is marked as failed. This is slightly
+    heuristic since vfork might be used in the future, but it provides a
+    higher level of assurance that no shells were executed as part of
+    command substitution with WRDE_NOCMD in effect. In addition it doesn't
+    require libpthread or libdl, instead we use the public implementation
+    namespace function __register_atfork (already part of the public ABI
+    for libpthread).
+    
+    Tested on x86_64 with no regressions.
