Sure, if you statically include individual libraries this isn't an
issue.  The result is a dynamically linked application with no
dependency on that library, however.  .la files will _NOT_ help you do
this.  I don't think libtool can even grasp the idea.

Ask the prelink package maintainer why the heck that's so.  It also
works on (offhand) SH, ARM, ia64, s390, s390x, powerpc64, x86-64.  I
don't know about m68k or hppa.  MIPS is a holdout.  It works, in other
words, nearly everywhere.  This information is months old.

I agree with you that it shouldn't be deprecated, as I said at the
beginning.  Sorry if I gave any different impression.
