Source is svn -CURRENT. There is no other option set than
WITHOUT_CLANG_IS_CC. Beside I use MALLOC_PRODUCTION=1

This happens on both 32-capable targets, amd64 and powerpc64.

I figured that there are at least three headers 'missing' so far in
src/lib32/usr/include:
- math.h
- fenv.h
- libutil.h

If I manually copy them to this location I can continue building until
/usr/bin/ld complains about not being configured for sysroots.
I just restarted the whole worldbuild again with the above mentionend
headers in place.

I'll take a few minutes ;)

TIA for your help!
