# 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
|
|
# unfortunately.
|
|
# 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.
