In some cases this will introduce cycles which could likely be cleaned
up by only depending on some unix tools instead of the whole autotools.
Rebuilding doesn't make much sense at this point since it just adds a subset
of base-devel which is still installed by default.
The program arguments should now be properly converted from unix to
Windows format, like done for non-MSYS programs. An indirect dependency
is now referenced by makedepends for avoiding build problems when using
its default provider.
