empty /etc/make.conf, clean /usr/obj, /usr/src symlink to
/opt/usr/RELENG_7/src

operating system: 
FreeBSD 7.0-STABLE FreeBSD 7.0-STABLE #0: Thu Mar  6 21:26:17 UTC 2008 
root at hostname:/pt/usr/obj/opt/usr/src/sys/W7_AMD64_ULE amd64

building world:
make -C /usr/src/ -j 16 buildworld TARGET_ARCH=amd64 TARGET=amd64

Finished succesful, installing world into separate directory:

make -C /usr/src/ installworld TARGET_ARCH=amd64 TARGET=amd64 DESTDIR=/mnt/crossinstall

Finished successful. Then I try to mergemaster standart configuration files:

mergemaster -a -i -m/usr/src/ -D/mnt/crossinstall -t/tmp/different_temproot

I have an error in building libc:

I tried to build libc manualy, (make -C /usr/src/lib/libc , clearing  /usr/obj before ), I have same
trouble.

I'm wrong somwhere or libc compilation somehow broken?
