Hi,


I wonder what you think about overriding the -Os compile flag for musl,
and hardcode it to -O2.

I think this makes sense since the functions in libc are so often used
that we want trade better performance at the cost of slightly bigger
binary.

This means that we override whatever user as set CFLAGS to
in /etc/abuild.conf

We already do this with zlib.

What do you think?
