[Patch/gas]: Check basename declaration for IVMS cross assembler

[Tristan Gingold]

Hi,

when configured for itanium VMS, tc-ia64.c calls basename().  But  
libiberty.h requires to check for its
declaration.  This patch add the check in gas configure.in

Checked on Darwin host and ia64-openvms target.

Ok to commit ?

Tristan.
