Summary: linker does not add "unused" module info
OS/Version: Mac OS X
on OSX the moduleInfo list (beteween _minfo_beg and _minfo_end) does not
include "unused" modules.
This is a nice optimization, and makes sense, but it would be nice to have a
way to disable it.
As it is now most unitest executing programs (programs that execute all
unittests of all modules) do not work, because their list of module to test is
empty (as they did not import it.
At minimum this behaviour should be documented, so that one knows it.
