M4RI is a library for fast arithmetic with dense matrices over the
Galois Field GF(2).

This subpackage contains libraries and header files for developing
applications that want to make use of libm4ri.

#
# 1. Need to disable SSE (this will cause the absence of -msse rather than
# the inclusion of -mno-sse, thankfully) - we cannot be sure if CPU has it.
#
# 2. Since the x86_64 specifies SSE2 as inclusive, not having -mno-sse
# anywhere is just fine.
#
# 3. Set cache size manually, because otherwise it will pick whatever the
# build host had, which is dumb. 32K:128K matches AMD T-Bred, and is also
# fitting within Core i7. Let's hope that's ok.
