    [gdb/testsuite] Handle with_set arch
    
    I realized that the more irregular output of show arch:
    ...
    (gdb) show arch^M
    The target architecture is set to "auto" (currently "i386").^M
    ...
    would be a problem for something like:
    ...
    with_set arch powerpc:common64 {}
    ...
    and indeed:
    ...
    (gdb) set arch powerpc:common64^M
    The target architecture is set to "powerpc:common64".^M
    (gdb) FAIL: gdb.base/foo.exp: set arch powerpc:common64
    ...
    and:
    ...
    (gdb) set arch set to "auto" (currently "i386")^M
    Undefined item: "set".^M
    ...
    
    Fix this in with_set by handling this type of output.
    
    Tested on x86_64-linux.
