[PATCH] Recognize and skip interpreter_p initialization in selftest.exp

[Fred Fish <fnf@specifix.com>]

With the latest development gcc and latest development gdb,
selftest.exp fails because the breakpoint at captured_main gets set at
the interpreter_p initialization, which isn't currently one of the
recognized patterns.  Apparently optimization has gotten better and
this code has been moved up the instruction stream:

  (gdb) br captured_main
  Breakpoint 1 at 0x807c714: file /src/latest/trunk/src/gdb/gdb/main.c, line 241.
  (gdb) run
  Starting program: /links/build/latest/trunk/i686-pc-linux-gnu/gdb/gdb/gdb
  Breakpoint 1, captured_main (data=0xbfdbb3f4) at /src/latest/trunk/src/gdb/gdb/main.c:241
  241       interpreter_p = xstrdup (context->interpreter_p);

	and skip over interpreter_p initialization.
