Commit Message

- KBUILD_LIBS was set but unused
- (pkg-config)_LIBS was also unused, replace it to get only the -L flags
- remember the -L flags in EXTRA_LDFLAGS
- also pass EXTRA_LDFLAGS to tests so they can find the lib

v2: trivial rebase on master

This is required on alpine with lua-5.3, and can be tested by setting
CONFIG_LUAPKG="lua5.3" in .config
Using the default lua version (5.1) does not require this as liblua.so
is populated in /usr/lib then.
