MBS_SUPPORT/ prepare_wc_buf issue

[Juan Manuel Guerrero]

I have tried to compile grep 2.7 on a system that has no multi byte support at
all.  The build failed because prepare_wc_buf is outside the #if MBS_SUPPORT
section.  The small patch below will fix the issue.

Regards,
Juan M. Guerrero

        * src/dfa.c [MBS_SUPPORT]: Compile prepare_wc_buf only if MBS_SUPPORT
        has been defined.
