flag-o-matic.eclass: allow further MIPS errata flags
* We were missing 24k, r5900, vr4120, vr4130, sb1 [0].
* Chuck in -Wa,-mfix-loongson2f-nop while at it. The topic of -Wa,* is an interesting
one, as we currently allow -Wl,*, so we should probably do the same for the assembler,
but punt that to another time.
Note that we use r5900 and -Wa,-mfix-loongson2f-nop for building stages...
Prompted by discussion with immolo (see also fad75a344cbaada57ae490c3e8f88cdd5b35dadc).
