You can use the [isnative] test to check to see if the test
is being run natively and then try executing the linked code.

For example in ld/testsuite/ld-elf/shared.exp there is the
following code to run a linked executable as part of the
mix_pic_and_non_pic procedure:

    if ![isnative] {
	unsupported "Run $exe fun undefined"
	return
     }

     set exec_output [run_host_cmd "tmpdir/$exe" ""]
     if {![string match "PASS" $exec_output]} {
	fail "Run $exe fun undefined"
     } else {
	pass "Run $exe fun undefined"
     }

Cheers
