[Notion-devel] [PATCH] lua-dectect.mk: empty pkgconfig --cflags/--libs are ok

[Olof J. <ol...@et...>]

As we have already determined the existence of lua, with the help
of pkg-config --exists, we should accept that empty responses
from pkg-config --cflags and pkg-config --libs are valid (this
has been seen in the wild).

Thanks to consus on IRC for reporting the issue.

(This change also makes minor formatting adjustments.)
