Unless I hear otherwise, I'll fix it by reverting the
Makefile.in change and applying this one instead:
-------------

Fix fsadm build failure a different way, so that fsadm doesn't use -llvm.

* lib/misc/util.c (last_path_component): Move definition to ...
* lib/misc/last-path-component.h (last_path_component): ...here.
New file.  Make the function "static inline".
* include/.symlinks: Add last-path-component.h.
* lib/misc/util.h (last_path_component): Remove declaration.
* tools/fsadm/fsadm.c: Include "last-path-component.h".
* tools/lvmcmdline.c: Likewise.
