[PATCH] xfs-cmds: fix parallel installs in include/ dirs

[Eric Sandeen]

This is for http://oss.sgi.com/bugzilla/show_bug.cgi?id=759
"fix parallel issue with include/ symlinks"

Doing something like "make -j2 install install-dev" would lead
to a race of removing & creating symlinks in include/

Thanks to Mike for reporting & suggesting the fix.
