Both of these are GCC version 5. GCC 5.1 is the first release of that,
GCC 5.2 the second, etc. Everyone should always use an as new release
as practical, since many bugs will be fixed, and nothing else changed.
See <https://gcc.gnu.org/develop.html#num_scheme>.
So, this means everyone using GCC 5 should be using the GCC 5.5 release!
If there is something about 5.1 that makes it produce bad kernels on
some arch, make that arch's Makefile complain? Same with binutils etc.
