    [gdb/testsuite] Run gdb.arch/ppc64-symtab-cordic.exp for --enable-targets=all
    
    While looking at test-case gdb.arch/ppc64-symtab-cordic.exp I realized that
    the test-case is too restrictive here:
    ...
    if {![istarget "powerpc*"] || ![is_lp64_target]} {
        verbose "Skipping powerpc64 separate debug file symtab test."
        return
    }
    ...
    and can also be run on x86_64-linux, if "set arch powerpc:common64" is
    supported, which is the case if we've build gdb with --enable-targets=all.
    
    Fix this by instead checking if powerpc:common64 is in the completion list for
    "set arch".
    
    This allows us to remove the 'untested "powerpc:common64 is not supported"'.
    
    While we're at it, clean up the test-case by using clean_restart.
    
    Tested on x86_64-linux.
