The build system thinks you're building a cross-compiler.  This is bad.

You need to get rid of some of the configure arguments.

 ~/ ../gcc-4.1.1/configure --prefix=/home/pmatos/gcc-bin
 --disable-altivec --enable-nls
 --without-included-gettext --with-system-zlib 
 --disable-werror --enable-secureplt --disable-libunwind-exceptions
 --enable-multilib --disable-libmudflap --disable-libssp
 --disable-libgcj --enable-shared --enable-threads=posix
 --enable-__cxa_atexit --enable-clocale=gnu

ought to do it.
