Building C++ libraries with GNU ld on HP-UX

[Alexandre Oliva]

GNU ld supports 64-bit object files on HP-UX.  But MLB libtool still
uses flags specific to the HP-UX linker when linking C++ libraries.
This patch fixes this problem.  It is reported to allow
GCC+libstdc++-v3 to bootstrap on a 64-bit HP-UX 11.0/pa system.  Ok to
install?

        * ltcf-cxx.sh [HP-UX GNU ld]: Don't use flags specific to the
        HP-UX linker.
