doltcompile does not reorder any flags passed to it; it merely
replaces the .lo filename with the appropriate object filename and
adds any necessary additional compiler flags (such as -fPIC -DPIC) to
the end of the command line.

dolt doesn't currently cover linking; libtool still does that. Since
-Wl,--as-needed appears at link time, libtool may still mess with it.
If and when I create a doltlink, it will not reorder flags either.
