Introduce support test procs: - supports_scalar_storage_order_attribute, and - supports_gnuc and use them in test-case gdb.base/endianity.exp. Tested on x86_64-linux with gcc-7.5.0, gcc-4.8.5, and clang 10.0.1. gdb/testsuite/ChangeLog: 2020-12-19 Tom de Vries <tdevries@suse.de> * lib/gdb.exp (supports_scalar_storage_order_attribute) (supports_gnuc): New proc. * gdb.base/endianity.exp: Define TEST_SSO. Eliminate test_compiler_info calls. Add unsupported message. * gdb.base/endianity.c: Use TEST_SSO.
