cmake tests whether the compiler can emit SSE, which is the wrongest of all
options. (At the very least, a build system would check the buildhost's actual
CPU feature set; while not great, there are convincable usecases for doing
that.)
Disable unconditional emission of -msse2 into the command line.
On x86_64 where SSE2 is always available, gcc already implies -msse2
anyway, so there should not be anything lost by removing this block
of makefilery.
