gcc: Fix preprocessor redefines for header pathes

When building for powerpc64 using musl as C library we get preprocessor
macro redefinition errors since gcc-configure-common.inc adds #define
of STANDARD_STARTFILE_PREFIX_1 and STANDARD_STARTFILE_PREFIX_2 to
gcc/defaults.h after ones added by a patch that ensures target gcc
headers included.

Since gcc-configure-common.inc included in every gcc recipe either
directly or indirectly, do_configure task is not disabled/deleted for
any of them (except gcc-source.inc) and there is no precondition that
skips gcc/defaults.h patching in
gcc-configure-common.inc::do_configure_prepend() we can just remove
conflicting parts of mentioned above patch to have single place where
start files prefixes defined in do_configure() task.
