[proaudio] QA Notice: strange behaviour

[Dominique Michel <dominique.michel@xxxxxxxxx>]

I noticed that QA Notice doesn't behave the same in my 2 gentoo boxes.

When merging raton in the new one, I get no QA Notice, but in the old
one, I get:

 * QA Notice: Package triggers severe warnings which indicate that it
 *            may exhibit random runtime failures.
 * callbacks.c:671:9: warning: incompatible implicit declaration of
   built-in function ‘sin’ [enabled by default]

This is with the same gcc version (4.7.2).
The only differences that can trigger this are the CFLAGS or the
FEATURES.

New box:
CFLAGS="-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm --param
l1-cache-size=32 --param l1-cache-line-size=64 --param l2-cache-size=512 -mtune=amdfam10 -O2 -pipe"
FEATURES="parallel-fetch userfetch"

Old box:
CFLAGS="-march=native -O2 -pipe -ggdb"
FEATURES="parallel-fetch userfetch splitdebug"
