You can avoid this trouble altogether by writing a simple test program
for your lib. At the end of the build commands, just compile and link it.
There are some facilities in Mingw-cross-env for test programs. That way,
you'll _always_ be sure that once your package builds, it will link correctly.

To get an example, you might want to look at the last few lines of "src/sdl.mk"
as well as "src/sdl-test.c".

Are you _really_ sure that this happened to you? This would be a serious
bug in the dependency resolution of GNU Make, or in our main Makefile.

A package should always rebuild after you changed one of its *.mk, *.patch
or *-test* files - even if version numbers and package checksums don't
change.

So if you are able to reproduce that issue, please describe exactly
what commands you issued and what results you got in between.
