Yes, this is valid, but redundant since -march=pentium3
implies -mcpu=pentium3
-mcpu uses only the i386 instruction set, but in a fashion adapted to the p3
architecture wrt cache size, cpu cycles cost,
You don't need both march and mcpu. Check /etc/make.conf
or man make for more information.

AFAIK it is. It does however, contain a bit of redundancy. According
to the GCC man page; "specifying -march=cpu-type implies
-mcpu=cpu-type." So the following should be identical:
