Configure ffmpeg to use freetype and fontconfig
if those packages are selected.
ffmpeg freetype support require fenv.h
which is not available in uClibc
except for uClibc on x86

V2 Added fontconfig to make freetype support more robust
I could not find a good way to do "or" in the make file
Is there something better than nesting and using two
ffmpeg_environment_has_fenv ?= y
statements? I'm not really happy about the temporary
