Yeah, relinking, not prelinking, sorry.

I guess something along the lines of make_relative_prefix might work, if a
twisted maze of soft links doesn't make it unworkable.  IIRC that's why libtool
decided to support DESTDIR but not arbitrary prefix changes.

In order to avoid relinking, you can configure with --enable-fast-install, but
I haven't checked this will work around the install-time complaint, and I'm
concerned that, at least on some systems, it might cause old preinstalled
dependency libraries to be used instead of just-built ones, in spite of GCC's
setting of SHLIB_PATH or equivalent.  I guess it may be worth a shot if you
want to operate outside libtool's (current) specs.

All that said, this is probably not the right forum to discuss bugs or suggest
improvements for libtool.  Heck, I haven't even been involved with libtool for
years, so I might as well back away slowly ;-)  IMHO, odds are better of having
it resolved for good (improved or rejected) if you take it upstream.  Now, if
you'd like to reopen this once it's in libtool's bug database, with a pointer
to it in âSee Alsoâ, just so that it's tracked in GCC's bug database, no
objections from me.
