[RFA] Delete breakpoint.c local variables

[Phil Muldoon <pmuldoon@redhat.com>]

While stepping through breakpoint.c longjmp breakpoint code, I noticed 
some small trivial unused local variables. Patch to fix.

2008-07-30  Phil Muldoon  <pmuldoon@redhat.com>

    * breakpoint.c (create_longjmp_breakpoint): Remove unused struct
    breakpoint.
    (set_longjmp_breakpoint): Likewise.
