Hello,

llvm-toolchain-7 currently FTBFS on hurd-i386, on openmp issues first,
which are being submitted upstream on https://reviews.llvm.org/D54079 ,
but after applying the fix for openmp I'm getting a weird issue:

1 error generated.


But the atomic file is there in the /mnt/compil/llvm-toolchain-7-7/libcxx/include directory given as LIBCXXABI_LIBCXX_INCLUDES::

€ ls -l /mnt/compil/llvm-toolchain-7-7/libcxx/include/atomic
-rw-r--r-- 1 samy samy 63749 sept. 17 12:02 /mnt/compil/llvm-toolchain-7-7/libcxx/include/atomic

Any idea what could be going wrong?
