MIPS: skip runtime detection for DSPr2 if -mdspr2 option is in CFLAGS
This provides a way to enable MIPS DSP ASE optimizations if running
under qemu-user (where /proc/cpuinfo contains information about the
host processor instead of the emulated one). Can be used for running
pixman test suite in qemu-user when having no access to real MIPS
hardware.
