gdal: reinplace didn't change anything in GNUmakefile

[ryandesign@…]

Using the patch from #15514, I see this message when upgrading gdal:

--->  Computing dependencies for gdal

As you see the port install completes anyway, so I don't know the implications of this ineffectual reinplace.

There's also a curious line in the portfile that doesn't appear to do anything:

	configure.args-append

Both changes occurred in r61243.

Presumably fixed by r74077, though it's hard to tell with all the whitespace changes.
