emulators/ppsspp: only enable on architectures with JIT support

Hi,

ppsspp fails to build on riscv64. Looking at the error log, I suspect
that other architectures may be affected.

The full list of architectures where a JIT is supported is:
arm aarch64 i386 amd64

mips32 is supposedly also supported but we don't run on that.
All the remaining JIT architectures are little endian, and ppsspp is
already disabled on big endian architectures. So NOT_FOR_ARCHS may seem
redundant now. Shall I keep it, as in the diff below, or shall I drop it?

ok?
