Provide dummy libraries for alpha-vms
alpha-dec-vms always loads a number of libraries, -limagelib, -lstarlet, and -lsys$public_vectors. When running the ld testsuite without a full cross-build environment, those libraries are missing and cause fails. This patch provides dummies, and tidies default.exp a little. * testsuite/config/default.exp: Provide dummy libraries for alpha-dec-vms. (compiler_supports): New proc. Use it for compiler tests. * testsuite/lib/ld-lib.exp (default_ld_assemble): Don't die if subdir not set. (run_ld_link_tests): Pass LDFLAGS to ld. * testsuite/ld-checks/checks.exp (section_check): Likewise. * testsuite/ld-scripts/assert.exp: Likewise. * testsuite/ld-scripts/extern.exp: Likewise. * testsuite/ld-scripts/log2.exp: Likewise. * testsuite/ld-scripts/map-address.exp: Likewise. * testsuite/ld-scripts/script.exp: Likewise. * testsuite/ld-scripts/sizeof.exp: Likewise.
