+# 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.
