Configure Errors While Trying to Compile binutils - makefile

Question

I'm trying to build a cross-compiler, but for some reason binutils is failing to compile. When I run make all, this is what I get after a while:
loading cache .././config.cache
checking whether to enable maintainer-specific portions of Makefiles... no
checking whether to install libbfd... no
checking for executable suffix... (cached) .dSYM
checking for gcc... (cached) /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
checking whether the C compiler (/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.
make: * [configure-opcodes] Error 1

What should I do to correct this?
