While we're in here, we should look at what the angstrom ones do 
correctly which is that BUILD_OPTIMIZATION is only for -native recipes.

And personally I'd like to see the -g flag (for both target and the 
rest) be a variable that can be tweaked as needed (for more or less 
debug in the area).

Having -g shouldn't hurt since the debugging symbols end up on the
-dbg packages. Why having it "disabled" by default?

In the case of host packages, I disable debug symbols (don't want, takes 
up space when shipping).  In the case of target stuff, we may want more 
debug info to be available.  Or one may want to have less because again, 
it takes up space when shipping.

I see but this could be overriden by distro, couldn't it?

That's why I'm asking for the -g part to be put into a variable so that 
it can be overriden easily, in all cases, without needing to know the 
special cases (ie glibc).

Why is glibc special anyway (or, why is the optimization in a
libc-specific conf file)?  It seems a bit bogus that the choice of your
C library would be having such a global impact on the compiler flags for
everything else.

There is some odd papering over that's going on to switch out a flag or 
two (and force -O2) for glibc (but not eglibc).  But my point is that 
today we have a few special case FULL_OPTIMIZATION_pn-'s and it'd be 
great to just not have to worry about that when setting the debug level 
we build with.

May be debugability can be expressed via another variable say
DEBUG_FLAGS or somesuch which can then we appended to global CFLAGS

With the caveat that I want to control native vs target at different 
levels, yes.

we can have a native counter part or calculate it using native override

Yeah, agreed.  Debugging is only tangentially related to optimization
and having the two things conflated in one variable is a bit of an
anachronism.  It certainly would be good to have that separated out in
some cleaner way.
