Only for static builds, and my cut/pasted compile flags didn't
consider that (by default, Myth=shared, FFmpeg=static).
Of course, the flag is Apple only, and not meant for dynamic libs:
% man gcc
On Darwin and Mac OS X systems, compile code so that it is not
relocatable, but that its external references are relocatable.
The resulting code is suitable for applications, but not shared
but building libavcodec*.dylib with it does seem to
cause no harm, and give working MMX acceleration.
At the moment, these hacks are _only_ needed for libavcodec,
so I think passing an extra config var into its .pro file is
tidier than setting it in CFLAGS everywhere.
