  New Revision: 62414

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62414

  Log:
    Avoid using `@` in macro substitution that confuses FreeBSD make
    
    ```
    making mjit_config.h
    make: Unknown modifier ' '
    make: Unclosed variable specification (expecting ')') for "Q" (value "") modifier
    /bin/sh: Syntax error: end of file unexpected (expecting "}")
    *** Error code 2
    
    Stop.
    ```
    
    The at sign probably conflicts the `:@temp@string@` modifier syntax
    supported by FreeBSD make.
