Very well. Here is the list of options to potentially turn off for Qt 4.8.5:
                              "-no-mmx"
                              "-no-3dnow"
                              "-no-sse"
                              "-no-sse2"
                              "-no-sse3"
                              "-no-ssse3"
                              "-no-sse4.1"
                              "-no-sse4.2"
                              "-no-avx"
                              "-no-neon"
So I can enable mmx, 3dnow, sse and sse2 on x86_64? Or only sse and sse2?
Or only sse2?

Qt 5.1.1 also has the following:
                              "-no-avx2"
                              "-no-mips_dsp"
                              "-no-mips_dspr2"
How about mips? We agreed to target it at loongson for the time being,
then could we enable one or both of the mips related options?
