MFC r239959:

Work around several warnings from clang in the xfs filesystem, when linking it statically into the kernel. With our gcc in base there are no warnings, so also remove the WERROR= from the module makefile. Noted by: Eir Nym MFC r240011: Partially revert r239959, after actually fixing most of the clang warnings in sys/gnu/fs/xfs. The only warnings that still need to be suppressed are those about array bound overruns of flexible array members in xfs_dir2_{block,sf}.c, which are too expensive (in terms of cascading code changes) to fix.

MFC r228994:

Disable several instances instances of clang's -Wself-assign warning. All of these are harmless, and are in fact used to shut up warnings from lint. While here, remove -Wno-missing-prototypes from the xfs module Makefile, as I could not reproduce those warnings either with gcc or clang.

Remove empty files and do nto try to build them.
