Autoconf fixes for linking on HPUX

[Warren_Baird/CSI at cimmetry.com]

Changelog:

        - added -fPIC to the LDDLLFLAGS line for HPUX; winegcc needs to 
pass -fPIC to the link line to keep the hp linker happy
        - set DLLEXT to .sl on hpux

Details:
        I took the somewhat lazy route here of just adding -fPIC 
explicitly if we're using hpux style link arguments, rather than adding a 
new test to see if we need to include -fPIC on the winegcc line.  My 
rationalle is that if we add support for another system that also needs 
-fPIC, we're almost certainly going to have to modify this section of the 
configure.ac, so I don't think it'd save much effort to add a new test.
