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.
