Attempting to build libxl causes Make to emit the following warnings
andrewcoop@andrewcoop:xen.git$ make -C tools/libxl all
...
Makefile:253: target `xenlight.pc' doesn't match the target pattern
Makefile:253: target `xlutil.pc' doesn't match the target pattern
...
because the static pattern rule is malformed. 'Makefile' as the only
prereq-pattern does not contain a pattern.
The rule ends up working because of the use of $@.in where $< should have been
used, but lacked any dependency between a $FOO.pc and its .in source file.
