Adding -pg to LDFLAGS doesn't help although I think you were right that
previously it was not being passed to the linker. The code is threaded

The profiling support might not be thread safe. While it may seem
counter-productive to program tuning, it is usually recommended to use
limited optimization, or no optimization at all.
If this _is_ a bug in libtool then I would like very much to help in
tracking it down, so any advice here is welcome.
As long as libtool is passing the -pg from CFLAGS to the compiler, and
the -pg from LFLAGS to the linker, and the correct startup module is
being used (indicated by a gmon.out file being written) then I think
that libtool is no longer the issue.
