Hmm, I don't have a universe to run with right now (out of town with
only my laptop), but I see in config/userspace/toolchain.lkc that
there's a CUSTOM_TOOLCHAIN_PREFIX as well as TOOLCHAIN_PREFIX which
defaults to CUSTOM_TOOLCHAIN_PREFIX if CUSTOM_TOOLCHAIN=y. However
there's not corresponding CUSTOM_TOOLCHAIN_CFLAGS.
Attached is a patch to the current CVS version (Version 1.7) of
config/userspace/toolchain.lkc that adds it. I haven't built with this
change (so your mileage _will_ vary), but see if the patch fixes the
issue. You'll want to apply the patch, run ltib -c to setup your custom
toolchain flags, then save/exit, retry ltib -c and inspect to see if
TOOLCHAIN_CFLAGS is no longer empty.
Hope this helps!
