package/gcc: remove uclibc-conf patch

This patch is present in Buildroot since a long time and has been rebased on
several version of gcc without beqing upstreamed.  Also it only concern
contrib/regression, which is not used at all during the build...

As suggested by Arnout [1], a test based on qemu_x86_defconfig has
been done without this patch and there is no regression.
