I don't really like this "solution", it just makes it the user's problem.

How likely is it that someone uses the latest version of dxe3gen, but is
somehow stuck with such an ancient (nearly 25 years old) version of gcc?  At
some point you'll just have to say, for gcc < X, use dxe3gen Y.

For DXE_LD_LIBRARY_PATH, that can be added easily as -L dir, and won't break
anything.  But not having this set should not be an error.

For DJDIR, there is only one valid place it can point to, and gcc already knows
where to find it.  I don't think a native gcc even works without DJDIR set.  So
it doesn't make sense to also parse it in dxe3gen.
