The one in $RESULT_TOP/lib is probably compiled for
the target; it's not the one the core-gcc needs.

I think I've seen this problem before, but I forget the circumstances.
Maybe gcc is confused, and thinks you're not building a
cross-compiler?
What kind of machine are you building on?

Somebody else posted a similar change; I'm attaching it,
since for some reasons his messages aren't being
archived by the mailing list archive at sources.redhat.com.

Maybe Khem Raj can comment... he's been building
ppc64 nptl toolchains.

Subject: [PATCH] pthreadtypes.h not found  NPTL patch 

I encountered a problem while building ppc64 NPTL toolchain. The copy 
operation for pthreadtypes.h was assuming that sysdeps has same sub 
directory name as
${ARCH} variable meant for linux part. However this is not true in case 
of ppc64/ppc where the sysdeps directory is called 'powerpc' similarily 
for sparc and sparc64

The build would fail complaining about 
nptl/sysdeps/unix/sysv/linux/ppc64/bits/pthreadtypes.h not founds

This patch corrects the problem. This patch may be incorporated into the 
NPTL patch.
