Yes, it looks that way to the eye doesn't it ... however a bit later in
the libtool script, when it puts together the actual command, it
reverses the order of everything, which means what went in the right way
round comes out the wrong way round.  I forgot to include this minor
relevant detail in the mail, but Gary and co. should already have
figured that out, right guys? :o)

The author of the original inst_prefix patch wasn't aware of this, so he
joined the two -L arguments together in the "right" order, namely
"-L/usr/lib -L/tmp/usr/lib" which after the reversal is the wrong order.

So we instead (in this patch) place them backwards so they come out
right in the actual relink command:

gcc -shared  .libs/libtest2.o  -Wl,--rpath -Wl,/opt/test/lib
-L/tmp/opt/test/lib -L/opt/test/lib -ltest1  -Wl,-soname
-Wl, -o .libs/

Have you ever, ever felt like this?
Had strange things happen?  Are you going round the twist?
