gcc-4.6.0 for arm-none-linux-gnueabi (bootstrap gcc)

Build bootstrap gcc:
need --disable-shared --disable-lto --disable-libquadmath --without-target-libiberty --without-target-zlib

If enabling these features, target may want to link crti.o ... (that is generated by later glibc)

With upcoming 4.6 building of target-libiberty and target-zlib is enabled (at
most platforms) per default.
It should be possible to disable this behavior e.g. with switches like:
--without-target-libiberty
--without-target-zlib

Previous versions did not try to build these libraries for cross compilers.
