1) --destdir='$(DESTDIR)' or --destdir="$(DESTDIR)".
But then we have the SCAN_OPTIONS situation again if someone
quotes DESTDIR.  Incidentally, I see

  if test "x$(DESTDIR)" = "x"; then \

in the makefile, which suffers from the same problem.

And if it was there when you were performing the builds,
then I have no idea what's going on.

2) Use

  Getopt::Long qw(:config gnu_getopt);

to make Getopt::Long fully GNU getopt_long() compatible.  Or
at least :config gnu_compat to change the behaviour of empty
--opt=.

Note however, according to my Getopt::Long man page empty
--opt is either GNU compatible or gives an error.  So in no
case it should eat the next option; something strange is
going on here.

3) Change $DESTDIR style from option to an argument and run
it just

  gtkdoc-rebase OPTIONS... $DESTDIR

Although rebase has no non-option arguments so this would
work, it's quite ugly and I don't like it.

4) Change the ($DESTDIR, $DESTDIR$TARGET_DIR) pair of
directories to ($TARGET_DIR, $DESTDIR$TARGET_DIR), that are
always defined, and let rebase extract $DESTDIR.

Not very nice either.  Passing two competely unrelated
directories as --html-dir and --dest-dir is a bit weird,
nevertheless it makes some sense with --relative (I have
a staging area, but in a different place I'm installing this
particular documentation).  In the new pair one directory
would have to be the tail of another.

-------------------------------------------------------------

The only approach that could get my is 2), the rest is just
a dump of random ideas.

I don't know what is the cause of the Getopt::Long behaviour
in jhbuild though.
