I played with that idea for a few mins, but unfortunately I found no
easy way in bash to deal with the quotes.
Assuming this syntax.

sys-apps/paxctl CFLAGS="-Os -fomit-frame-pointer" 
sys-devel/gdb CFLAGS="-O2 -g3"
app-misc/beep FEATURES="sfperms sandbox" LDFLAGS="-Wl,-z,now
-Wl,-z,relro"
dev-libs/openssl CFLAGS="-O3 -fno-omit-frame-pointer -m32"
..

Maybe somebody else is motivated to do it from the basic idea. I gave up
and settled for the easy way out of package.cflags package.ldflags here
locally.
