"unresolved" as a test result means runtest returns an error, which can be confusing when there is no apparent error unless you look in .log files. In particular many tests are skipped without reporting an error if no target C compiler is found, but if a target C compiler is found but won't compile a testcase for some reason we used to mark the test as unresolved. Which is no more worthy of an error than when lacking a C compiler entirely. * testsuite/ld-cdtest/cdtest.exp, * testsuite/ld-checks/checks.exp, * testsuite/ld-elf/binutils.exp, * testsuite/ld-elf/compress.exp, * testsuite/ld-elf/dwarf.exp, * testsuite/ld-elf/exclude.exp, * testsuite/ld-elf/frame.exp, * testsuite/ld-elf/indirect.exp, * testsuite/ld-elf/linux-x86.exp, * testsuite/ld-elf/sec-to-seg.exp, * testsuite/ld-elf/tls_common.exp, * testsuite/ld-elfcomm/elfcomm.exp, * testsuite/ld-elfvers/vers.exp, * testsuite/ld-elfvsb/elfvsb.exp, * testsuite/ld-elfweak/elfweak.exp, * testsuite/ld-ifunc/binutils.exp, * testsuite/ld-mips-elf/mips-elf-flags.exp, * testsuite/ld-misc/defsym.exp, * testsuite/ld-mn10300/mn10300.exp, * testsuite/ld-plugin/lto.exp, * testsuite/ld-plugin/plugin.exp, * testsuite/ld-scripts/align.exp, * testsuite/ld-scripts/assert.exp, * testsuite/ld-scripts/crossref.exp, * testsuite/ld-scripts/defined.exp, * testsuite/ld-scripts/extern.exp, * testsuite/ld-scripts/log2.exp, * testsuite/ld-scripts/map-address.exp, * testsuite/ld-scripts/phdrs.exp, * testsuite/ld-scripts/phdrs2.exp, * testsuite/ld-scripts/script.exp, * testsuite/ld-scripts/section-flags.exp, * testsuite/ld-scripts/sizeof.exp, * testsuite/ld-scripts/weak.exp, * testsuite/ld-selective/selective.exp, * testsuite/ld-sh/sh.exp, * testsuite/ld-shared/shared.exp, * testsuite/ld-srec/srec.exp, * testsuite/ld-tic6x/tic6x.exp, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-undefined/weak-undef.exp, * testsuite/lib/ld-lib.exp: Don't use unresolved except after perror.
