gold: Remove the circular IFUNC dependency in ifuncmain6pie
On Fedora 33 x86-64 with glibc 2.32-3, ifuncmain6pie failed with: ./ifuncmain6pie: IFUNC symbol 'foo' referenced in './ifuncmod6.so' is defined in the executable and creates an unsatisfiable circular dependency. FAIL ifuncmain6pie (exit status: 127) Remove non-JUMP_SLOT relocations against foo in ifuncmod6.so, which trigger the circular IFUNC dependency. * testsuite/ifuncmain6pie.c: Remove non-JUMP_SLOT relocations against foo in ifuncmod6.so. * testsuite/ifuncmod6.c: Likewise.
