Suggestions:
1) Use HP ld. As noted in documentation, there are problems with GNU ld.
2) Gmp and mpfr need to be 64-bit. Make sure they build and check
successfully.
3) Initially, you should probably just build C using a GCC branch (e.g.
4.0.4) that doesn't depend on gmp and mpfr. Then, install and build
a newer version.
The error indicates a problem with the precompiled GCC used as a bootstrap
compiler.
