    [gdb/testsuite] Fix gdb.base/endianity.exp with gcc-4.8

    When running test-case gdb.base/endianity.exp using gcc-4.8, we get:
    ...
    (gdb) x/x &o.v^M
    0x7fffffffd120: 0x00000004^M
    (gdb) XFAIL: gdb.base/endianity.exp: x/x &o.v
    x/xh &o.w^M
    0x7fffffffd124: 0x0003^M
    (gdb) FAIL: gdb.base/endianity.exp: x/xh &o.w
    ...

    The gcc 4.8 compiler does not support the scalar_storage_order attribute,
so
    the testcase is compiled without that attribute, and the expected results
are
    different.

    Fix this by rather than xfailing, skipping the tests if the compiler does
not
    support the scalar_storage_order attribute.

    Tested on x86_64-linux, with gcc-4.8, gcc-7, and clang-10.
