hardened: use LD_PIE_SPEC only if defined

sol2.h may define LINK_PIE_SPEC and leave LD_PIE_SPEC undefined, but
gcc.cc will only provide a LD_PIE_SPEC definition if LINK_PIE_SPEC is
not defined, and thenit uses LD_PIE_SPEC guarded by #ifdef HAVE_LD_PIE
only.  Add LD_PIE_SPEC to the guard.


gcc/ChangeLog

	* gcc.cc (process_command): Use LD_PIE_SPEC only if defined.
