sframe: Use UNRESOLVED instead of FAIL

sframe: Use UNRESOLVED instead of FAIL

Fix for PR ld/33784.

The SFrame test for PR ld/33401 is a two-step link test where the
second link depends on the output of the first. In the first step, the
linker process generates R_*_NONE relocs for .sframe section, while
the second link process should pass without any issue.

This patch reworks the PR ld/33401 test by removing the call to
run_cc_link_tests, and use individual command invocation for
compilation, assembling and linking. It introduces the UNRESOLVED
status if the first step contains a linking or assembling error. The
UNTESTED status is emitted if the first stage doesn't produce R_*_NONE
relocs in .sframe section to test the original issue.
