klibc - Dec 2008 - klibc broken on ppc with linux-2.6.27 and workaround

Compilation was ok with klibc-1.5.10 on linux-2.6.25.
Distrib does not matter as it is inside a chroot a la LSF

With the upgrade to linux-2.6.27 it broke on 1.5.10 (I try too the last
1.5.14) with
make[1]: Entering directory `/usr/src/klibc-1.5.14'

...

As a workaround I have symlinked the directories removed in 2.6.27 and it
now compile
 cd /usr/src/linux-2.6.27/arch && ln -sf powerpc ppc
 cd /usr/src/linux-2.6.27/include && ln -sf arch-powerpc arch-ppc

I have seen that Gentoo use a different system and a klibcasmarch.patch
http://sources.gentoo.org/viewcvs.py/gentoo-x86/dev-libs/klibc/klibc-1.5.12.ebuild?rev=1.1&view=markup
A bit complicated for me.

I guess I really should spend some TLC on klibc... I haven't given it
too much time, and with all the header changing around lately it gets
tricky.

The Right Thing[TM] is probably to use the exported header stuff for
klibc, assuming it contains sufficient information.
