runtime: add ppc and s390 to 32 build constraints for gccgo

Theses are not supported by the go compiler but it may helps porting to gccgo.

I have no idea if this change is correct, but it is weird that
os_linux32.go and os_linux64.go should have ppc & s390 but not all other
files gated to 32bits in the same package.
