Here's a patch that uses the +cdp linker flag to close the security
issue with the fallback path encoded into the SOM binaries, by adding
another libtool property 'fix_hardcoded_libdir_flag_spec', only used for
hppa-hpux (32bit). It is configure-checked if compiler/linker do support
this flag.

This allows for hardcode_action=immediate and fast_install=yes, required
for DESTDIR support.

tests/deplibs-ident.at has to filter this flag, as it would lead to
false positives.

The same 12 tests as before are turned from SKIP/XFAIL to PASS on all
the setups as before, with one exception: It is collect2 of gcc-3.0.1 on
hppa-hpux10 here, which erroneously interprets -Wl,+cdp and fails to
find libraries. So no tests do change their result in this setup.

Thank you!
