Use -Bsymbolic for shared libraries on HP-UX and Solaris.

These platforms are also subject to the mis-linking problem addressed
in commit e3d77ea6b.  It's not clear whether we could solve it with
a solution equivalent to GNU ld's version scripts, but -Bsymbolic
appears to fix it, so let's use that.

Like the previous commit, back-patch as far as v10.
