I understand.  What I was suggesting is that those run-time tests be
compiled and linked if you have $CC available, eg. i686-linux-gnu-gcc
installed on your x86_64-linux-gnu system.  run_ld_link_exec_tests now
tests isnative itself before running a test binary.

The downside of making a change like the following is that if your
system does have i686-linux-gnu-gcc available but not the
corresponding C library then you'll get more linker testsuite
