This PR is a placeholder for known limitations regarding the weak support
of the HP PA_RISC target under HP-UX 11 and later. This support is available
in GCC 3.3 and later.
Weak support on this target is implemented using SOM secondary definition
(sdef) symbols. While sdef symbols have some of the attributes of weak
symbols as defined in the ELF SYSV ABI, they differ in behavior in the
following ways:
1) Undefined sdef symbols generate linker and/or runtime errors.
2) The first definition seen by the linker is used (i.e., a primary
definition doesn't replace an earlier secondary definition).
3) Secondary symbols in objects linked into a shared object become
primary symbols (sdef symbols never appear in shared objects).
