Support for getting (i)MDCT output multiplied by a constant scaling factor.
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

Don't set mm_flags in fft-test, since it doesn't do anything anyway.

Define mm_flags/support to be 0 on architectures where they don't exist.
Make sure we don't try to set them if that's the case.
This lets dct-test and fft-test build with --disable-mmx on x86, but not yet on ARM.
