For gcc-3, you should configure with '--enable-languages=c', then use 'make' and 'make install'
In order for the '--with-inhibit-libc' to work, you should have a file 't-inhibit-libc' in
gcc-3.0.4/gcc/config/arm/ (created by the softfloat patch)
After you then have compile gcc and glibc, you can configure with '--enable-languages=<any language you like>'

In order for the multilib version to work completely, you should probably compile glibc multiple times
(with different options), but I've no experience with that.
