[issue21282] setup.py: More informative error msg for modules which built but failed import check

New submission from Lukas Vacek:

Hey,

Currently when a module builds successfully during cpython build but it can't be imported (import check around line 330 in setup.py) the module shows in "Failed to build these modules: " which can be misleading.

Especially when linking against libraries in non-standard locations the user would set LD_FLAGS and CPPFLAGS and then ... wonder why the cpython build process is not picking the libraries up and the module is not built.

I think the modules which *have built* but were removed because of a failed import check should be marked as such so the user knows what happens and can take appropriate actions (set LD_LIBRARY_PATH as well, for example).

A patch attached - it's a very simple change (about 10 lines), created with "hg export".

Thanks,
Lucas
