[Buildroot] [PATCH] package/lua-cqueues: needs host-m4

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

The lua-cqueues build system uses m4 during the build:

cd /home/test/autobuild/run/instance-1/output/build/lua-cqueues-rel-20161215/src && m4 /home/test/autobuild/run/instance-1/output/build/lua-cqueues-rel-20161215/src/errno.c.m4 >| /home/test/autobuild/run/instance-1/output/build/lua-cqueues-rel-20161215/src/errno.c.tmp

Therefore, the package should depend on host-m4. This has been
detected using per-package directory support, but a minimal defconfig
with just lua and lua-cqueues on a system that doesn't have m4
installed system-wide also exhibits the issue.
