This is a known issue when using the HP assembler.  Configure GCC
with the GNU assembler and the HP linker.  This provides the best
support for C++.

Weak support is not available when using the HP assembler.  Without
weak support, there are significant problems with vtable support and
template instantiation.  3.3 is worse than 3.[0-2] in this respect.
There is weak support under HP-UX 11 using the GNU assembler.  In
my opinion, the ia64 ABI adopted for C++ only works when a target
has one-only support.  There is some possibility that we might be
able to provide one-only support using the GNU assembler under HP-UX
10.20.  This would use the linkers support for common symbols.
Again however, this won't work with the HP assembler (HP Fortran
doesn't use the HP assembler).

The GNU linker has a number of problems (e.g., -static doesn't work).
Thus, it's better to use HP ld at this time.
