improve configure's target arch matching
most notably, it was failing to match sh4-*, etc., but in general the explicit matching of hyphens for some archs was problematic because it failed to accept simply the musl-style arch name (without a gcc-style tuple) as an input. the original motivation of matching hyphens was to prevent incorrectly identifying a 64-bit arch as the corresponding 32-bit arch (e.g. mips* matching mips64) but this is easily fixed by simply checking (and for now, rejecting as unsupported) the relevant 64-bit archs.
