[Bug nptl/11505] New: nptl/sysdeps/x86_64 doesn't honor --with-binutils settings.

hi,

the nptl/sysdeps/x86_64/configure uses 'CC -c' to detect .cfi_personality
support in AS and such combination doesn't work with custom --with-binutils
settings.

i've discovered this during setup recent glibc for 'make install-headers'
for crosscompiler on old redhat disto.

changing 'CC -c' invocation to 'AS' in configure fixes the problem.

No, it doesn't solve ting.  We always use CC.  By testing with AS
inconsistencies are introduced.  Using --with-binutils should add this to the
gcc command line.  If this doesn't work you have to investigate that part.

there's no CC inside --with-binutils directory. there's only a tree with kernel
headers and binutils for target architecture. at this point i'm configuring
glibc with --enable-hacker-mode --disable-sanity-checks for installing glibc's
headers with `make cross-compiling=yes install-headers`.
finally, the configure script detects an old gcc-4.1.2-42.el5 for build/host
and recent as/ld for target:

(...)

imho, using CC for detecting target assembler features at `cross-compiling=yes
install-headers` stage is a bug.

ps).
there's another problem with detecting cpuid.h at this stage.
worked around with ac_cv_header_cupid_h=yes forcing.
