   We could use ldd for this but it depends on LD_LIBRARY_PATH being

   we need to support different switches for the GNU and HP linkers.
   We can't check TARGET_GNU_LD in collect2, so we need a different
   test.  The +Accept switch is always the first switch when we are
   using the HP linker (see define for LINK_SPEC).  Checking for it
   is a somewhat fragile as it depends on internal details of the
   collect2 program but it is better than testing ld_file_name.

   FIXME: The GNU linker is broken.  The -init/-fini switches don't
   work and ldd can't determine the dynamic dependences of executables
   linked with GNU ld.  The init and fini routines are not executed
   although DT_INIT and DT_FINI appear ok.  As a result, defining
   LD_INIT_SWITCH and LD_FINI_SWITCH causes more harm than good when
   using GNU ld.  However, the definitions appear to work fine with
   the HP linker.  */
