testsuite compile break in master

Hi,

the testsuite does not compile anymore:
qemu-sparc_uclibc_sparc/usr/include/ -isystem
/home/wbx/adk/toolchain_qemu-sparc_uclibc_sparc/usr/lib/gcc/sparc-openadk-linux-uclibc/4.9.2/include-fixed
-isystem

toolchain_build_qemu-sparc_uclibc_sparc/w-uClibc-0.9.34-git-1/uClibc-0.9.34-git/.config

UCLIBC_HAS_THREADS_NATIVE=y
UCLIBC_HAS_THREADS=y
PTHREADS_DEBUG_SUPPORT=y

UCLIBC_HAS_THREADS_NATIVE is active, but atomic.h is not installed.

Any idea?

best regards
