This issue should already be resolved by r40303.

The other issue (needing to use $GRASS_PYTHON for actual usage) is
still outstanding.

No; I merely commented that having something in scripts try to use
wxGUI modules would fail due to the order in which they were built.

This should no longer be an issue, and even if it was, changing the
order is the wrong solution. We shouldn't be relying upon the order in
which the subdirectories are built any more than is strictly
necessary.

The only ordering which should be required is:

demolocation + tools + include > lib > [everything else] > locale + man > macosx

The ones at the beginning inherently form the foundation on which the
rest of GRASS is built. The ones at the end are based upon GRASS as a
whole (locale needs to extract translatable strings from C files, some
of which need are generated from non-C files, man builds global and
category indices, macosx creates a GRASS package).

The rest should ideally be able to be built in any order. E.g. I
recently added tools/g.echo[1] to convert MSys pathnames to Windows
pathnames during the build process (previously, g.dirseps was being
used, but that doesn't work when you're creating a manpage for a
subdirectory of lib as g.dirseps hasn't been built yet, and it can't
be built before lib/gis).

[1] g.echo just echoes its argument, but MSys automatically converts
MSys paths to Windows paths when running anything which isn't part of
MSys.
