Rather than selectively merging one change, I think you should:
* Merge the change to use a URL instead of an FSF postal address in the
header from glibc to GCC.
* Merge indentation fixes from glibc to GCC (it looks like there are some
places where glibc is indenting with tabs but GCC is using spaces).
* Once the only differences are substantive changes that were made in GCC
but not in glibc, copy the GCC version to glibc to get them back in sync.
