testsuite/lib/scanasm.exp:hidden-scan-for returns an empty string
for object formats other than elf and mach-o. This causes any
tests using scan-not-hidden to fail. Instead, they should be
UNRESOLVED when how to test for hidden symbols on that object format
is not known. Likewise, scan-hidden should also yield UNRESOLVED
in this case.
The problem arises for systems where objdump is unavailable or
fails to identify the file format - which may in fact be ELF with
visibility support but no working ELF objdump. It can also be reproduced
on ELF systems with working objdump by changing the regexp
in hidden-scan-for to "" for ELF.
