This was rejected before:
And i'm back to my original question, what's the specific need for this?
Even for eglibc/glibc we force -O2 for example.
If there's a very valid (like, it breaks!) reason for this we can look
for a way to address it, but as-is i say NAK.
If you look at uClibc's Rules.mak file you'll see there are lots of
OPTIMIZATION/CPU_CFLAGS (and other) conditionals that could be undone by
this and lead to unexpected results.
