    bsd.{sys,kern}.mk: Fix syntax error in pattern 'gcc[5-]*'
    
    If ${_WCCVER} doesn't match the 'gcc[5-]*' pattern, bmake would generate
    this fatal error:
    
    ```
    Unfinished character list in pattern 'gcc[5-]*' of modifier ':M'
    	while evaluating variable "_WCCVER" with value "gcc100"
    make: Fatal errors encountered -- cannot continue
    ```
    
    Interestingly, this pattern works as expected if there is match.  This
    is because bmake matches the pattern along the parsing; it doesn't
    validate the pattern syntax before matching it.  The bmake code requires
    that both the range begin and end be specified.  So this is actually a
    bug in the bmake code.  See also contrib/bmake/str.c:Str_Match().
