[dmd-internals] Test with the -lib flag

[Jacob Carlborg via dmd-internals]

I need to create a test for the DMD test suite that consists of two files, one which need to be compiled with the -lib flag and one without, which links with the library. There’s the EXTRA_SOURCES test variable but as far as I can see it’s not possible to specify any flags for the extra sources.

What’s the best way to solve this?
