This is not really infinite, it just seems that way.  It is building using
multi-lib so that it has libraries for every possible combination.  ie.
big-little endian, etc.  Try configuring with --disable-multilib

Use "make cross" and "make install-cross" as they are the recommended
methods for egcs.  They will, however, only build LANGUAGES="c c++".  If
you need f77 try hacking the top level Makefile.in.

I'm not an expert on this stuff, but I have successfully build a
sparc-sun-solaris2.6->powerpc-unknown-eabi tool chain.
