Patch to support IA64 HP-UX

[Steve Ellcey]

I have put together a libtool.m4 patch to support the HP-UX IA64
(Itanium) platform and would like to have it checked in if it is
acceptable.  IA64 HP-UX differs from the PA platform in a number of ways
such as using the .so suffix instead of .sl.  I also took advantage of
some new (HP-UX) features to make IA64 HP-UX look more like other ELF
platforms.  These include using LD_LIBRARY_PATH instead of SHLIB_PATH
and using -L to hardcode paths instead of +b.  SHLIB_PATH and +b are
still supported on IA64 but I chose not to use them in order to create a
more 'standard' type configuration.

I ran the libtool test suite and it does not pass completely (fails 6 of
75 tests) but the other HP-UX platforms don't seem to pass completely
either so I was hoping this could be checked in anyway and fixes could
be added later once the basic support is in.  I spent the better part of
two days trying to get the full test suite to pass and I don't know if I
can afford to spend any more time on it right now, but I would like to
get some support for IA64 HP-UX into the official source tree if
possible.
