I had the same issue. I started to dig into the gcc build system, but
quickly gave up, this headers inclusion is dynamically generated from
stuff determined at configure-time. I just tried to build gcc 4.5.0
(not yet in ct-ng) and it worked fine, however, ia-64 is still broken.
For information [yes, I know, it's not in the hg repo]:

[ALL  ]    In file included from
/x/bare/targets/src/gcc-4.5.0/libgcc/../gcc/config/ia64/unwind-ia64.c:34:0:
[ERROR]    /y/ia64-unknown-elf/build/build-cc-core-baremetal/./gcc/include/unwind.h:214:20:
fatal error: stdlib.h: No such file or directory

GCC 4.4.3 dies on the same error. I would have tried 4.4.4RC, but the
directory seems to be gone from gnu.ftp.org :(.
