 17# In other words, "make userfaultfd" is supposed to fail to build at all,
 18# because this Makefile only supports either "make" (all), or "make /full/path".
 19# However,  the built-in rules, if not suppressed, will pick up CFLAGS and the
 20# initial LDLIBS (but not the target-specific LDLIBS, because those are only
 21# set for the full path target!). This causes it to get pretty far into building
 22# things despite using incorrect values such as an *occasionally* incomplete
 23# LDLIBS.
