Microblaze simulator - Fix missing prototype

[Sergio Durigan Junior]

Hi Joel,

Same comment from last e-mail: please send the patches to
gdb-patches@sourceware.org.  I am replying this e-mail to the
appropriate list, with comments about your patch, but please send other
patches to that list.

The `_initialize*' routines are treated specially by the Makefile, when
you build the project.  They cannot be made static because they are
called from another source file.  Take a look at gdb/Makefile.in, and
search for the rule `init.c:'.

There should be a space between the function name and the open paren.

I am not a maintainer, but this change seems pretty trivial to me so
that it can be committed without an explicit approval.

Thanks,
