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.
