You must then have had the earlier C library preinstalled...

Producing a GCC generally requires the target C library being present
during the build for :

- fixing the target headers (fixinc phase)
- investigating the libraries for available functions (producing the 
extra libs)
- using the headers when compiling the extra libs for the target

So you are doing something really wrong :(

With your $target  most people use 'newlib' as the C library and if one
uses that, producing the GCC should succeed without a pre-existing
target C library.  Only installing the generic newlib headers or 
building newlib
with GCC (copying/symlinking 'newlib' and 'libgloss' from newlib srcs
into the main GCC src dir) are required...  But then one must tell that
via the '--with-newlib' option in GCC configure!
