Improve IFUNC check [BZ #25506]
GNU ld's RISCV port does not support IFUNC. ld -no-pie produces no relocation and the test passed incorrectly. Be more rigid by testing IRELATIVE explicitly. Tested-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
