gcc does not use the pic version libiberty.a if built

["Peter S. Mazinger" <ps dot m at gmx dot net>]

Hello!

gcc builds 2 versions of libiberty.a, one w/ pic and one w/o, but uses 
only the non-pic version later for the intermediate execs (gen*)
On a system, that supports text relocations, but text relocation is 
not allowed due to restrictions in libc or kernel these binaries will all 
fail if built as PIE (the binaries end up w/ text relocations)

The same can also be observed in binutils and RedHat "circumvents" this, 
by rebuilding libiberty.a a second time separately by adding -fPIC to 
CFLAGS (because this libiberty.a is used system-wide, and not the one 
provided by gcc)

The attached patch solves the problem by overwriting the non-pic version 
w/ the pic version, if the pic version is built.

	* if pic version of libiberty.a is built, make also use of it
