faad2: add configurable fixed point build

Browse Source 
Change the faad build to use fixed point math if emulated floating point
is in use (based on CONFIG_SOFT_FLOAT). Adds a config option to force
the use of floating point math.

help
By default, libfaad2 will be built to use fixed point rather
than floating point math if emulated floating point operations
are being used. (See the CONFIG_SOFT_FLOAT option.) Set this
option if you would like to use floating point math regardless
of whether floating point emulation is in use.
For the best real-time decoding ability, leave this option off.
