Sure, I can do that.

You mean, even if it won't be used, compute the libdir from either
DXE_LD_LIBRARY_PATH or DJDIR and add it as -L ?

OK, can do.

With those in mind, what do you think about compatibility with old
gcc versions? I found that at least gcc-2.95 doesn't work after this
patch possibly because it doesn't handle -T dxe.ld on the command
line. (I only tested gcc-3.4.6, maybe older ones don't work either.)
