Another HP-UX IA64 Build patch

[Steve Ellcey <sje@cup.hp.com>]

Here is the second of my IA64 HP-UX build patches.  This one involves
the declaration of basename() in include/libiberty.h.  What do people
think about using the prototype version whenever we are compiling with
GCC?

I did that rather than checking for HP-UX because some HP-UX systems
(old PA ones) cannot handle the prototype but it seems like GCC should
always be able to deal with it and it is when using GCC that "-Wall
-Werror" will be set so I thought it might be better to check for GCC
rather than HP-UX.  Does this seem reasonable to people?  Maybe we could
remove some of the OS checks if we checked for GCC instead.

Tested on IA64 HP-UX.
