[rfa/testsuite] more selftest.exp tweaking

[David Carlton <carlton@math.stanford.edu>]

I just noticed that my compiler (GCC 3.1 -O2) reorders some of the new
sysroot stuff in captured_main to a location where selftest.exp sees
it.  I'm almost positive that seeing this is legitimate, not a bug in
GDB.

Here's a patch to allow it; OK to commit?  Tested on
i686-pc-linux-gnu/GCC 3.1 -O2/DWARF-2.

(Selftest is a pain.  Sigh.)

	* gdb.base/selftest.exp (do_steps_and_nexts): Allow gdb_sysroot.
