[PATCH] cc1 and cc1plus had about 20 mbytes of debug information each, in the final redistributable form. This patch strips those two binaries yielding a savings of about 40 mbytes per SDK.

We recently added logic to conf/distro/include/sane-toolchain-* to 
handle the debug level via DEBUG_LEVEL.  Would you mind adding a 
DEBUG_LEVEL_HOST to conf/bitbake.conf and making BUILD_OPTIMIZATION obey 
that instead so that we can drop debug info from all of them?  Thanks.

Tom,

Thanks.  On this one, please just take it over.  I am still coming up to
speed, and am not able to decipher what you want in a way that will make you
happy.

I know its only a few lines, and you'll want it done a certain way anyway.

Thanks tons.   The disk savings is substantial and worth your time.

Next time I'll be better positioned to help.

Dick
