Targets that have just -march= and -mtune=:
gcn, mips, riscv, s390
Targets that have just -march= and -mcpu=:
csky, iq2000, nds32
Targets that have just -mcpu= and -mtune=:
alpha, arc, rs6000, sparc, visium
Targets that have just -mcpu=:
bfin, frv, m32c, microblaze, msp430, rl78, rx, tilegx, tilepro
Targets that have just -mtune=:
