# Robin H. Johnson <robbat2@gentoo.org>, 12 Nov 2007:
# This still needs major work.
# But it is significently better than the previous version.
# In that it will now build on biarch systems, such as ppc64-32ul.

# NOTES:
# ======
# We need to bring in the kernel sources seperately
# Because they have to be configured in a way that differs from the copy in
# /usr/src/. The sys-kernel/linux-headers are too stripped down to use
# unfortunetly.
# This will be able to go away once the klibc author updates his code
# to build again the headers provided by the kernel's 'headers_install' target.
