HP-UX 11.x patch to call C++ static constructors at dlopen()

[Harri Pasanen]

This patch fixes PR 8360

http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8360

Patch is against gcc 3.2, should apply directly to gcc-3_2-branch.

This works for me on HP-UX 11.00, 64 bit kernel, 32 bit gcc, gcc -v says:

Configured with: ../gcc-3.2/configure --prefix=/opt/gcc32 --with-gnu-as 
--with-as=/usr/gnu/bin/as --enable-threads=posix --enable-languages=c,c++
Thread model: posix
gcc version 3.2

Thanks to David Edelsohn and John David Anglin for pointers.
