With the new shell script in this patch, we have a place to fix-up
libtool-isms so that the normal LoadModule statement works.  This
version of the script fixes up the install on AIX, HP-UX, and Tru64.

Beyond the function in this patch, the next step is to have it
installed in prefix/build and teach apxs to use instdso when it
installs DSOs.

I have only tested this on AIX thus far.  I hesitate to test it much
further before people have a chance to comment on things they might
not like.

Have fun...
