link_spec.patch

From: Christian Prochaska <christian.prochaska@genode-labs.com>

Enable LINK_SPEC customization via configure arguments

We add a hook for sneaking our custom LINK_SPEC definition into the GCC
configure process by uncommentig the 'host_xm_include_list'. This enables us
to supply a custom header file to be included into 'gcc/config.h' defining
the 'LINK_SPEC' macro. This macro expresses the policy of how the GCC
frontend invokes 'ld' on multiarch platforms. I.e., on x86, we need to pass
'-melf_i386' to 'ld' when building in '-m32' mode.
