That test shouldn't be a useflag in the first place, that there should
be a TESTDEPEND and a dedicatated function defined in PMS to let the
ebuild check if src_test will be executed. 'test' as we use it is
pretty much a hack.

Another note, 'if use test; then' is often very similar in nature to
conditional patching and should be avoided where reasonably possible.


Either way, I'm against adding test to IMPLICIT_IUSE on the basis of 'I
was lazy and want to continue to do so'.
