Position-dependent linker flags have not yet been implemented in
libtool.

Hmm, that looks very fishy:

and won't do what you want.  Libtool causes all convenience archives to
be linked with --whole-archive.  Are 
  ../lib/bf/src/libbf.la
  ../lib/ot/src/libot.la
  ../lib/fm/src/libfm.la

convenience archives (noinst_LTLIBRARIES)?  If yes, then what you want
should work out of the box.  If no, where are they to be installed
(are they lib_LTLIBRARIES)?

Cheers,
Ralf
