flac: unbreak powerpc e500 support

Browse Source 
Add patch to avoid the enable/disable-debug options from unsetting -g
from CFLAGS in an incorrect way which breaks -mfloat-gprs=X (translit to
-mfloatprs=X).
It's possible to affect other less common CFLAGS with a '-g' in any
position.

Upstream status: sent different patch (configure.ac) - to avoid
autoreconfiguring.

The sed expression is wrong, any flags with '-g' in any position gets
zapped, for example:
-mfloat-gprs=double (for powerpc e500) -> -mfloatprs=double.
Which gives build errors and is perfectly valid in real use scenarios to
switch from e500v1 (single precision) code to e500v2 (double precision) code.
