[PATCH RFA] Make gdb.base/shlib-call.exp work for AIX

[Kevin Buettner <kevinb@redhat.com>]

The patch below makes some adjustments to gdb.base/shlib-call.exp so
that it will work for AIX.

Okay to commit?

	* gdb.base/shlib-call.exp (additional_flags): AIX doesn't need
	``-fpic'' when compiling files comprising a shared library, but
	it does need additional linker flags in order to find shared
	libraries at run time.
