[RFA] tweak for gdb.asm/asm-source.exp

[Michael Snyder <msnyder at cygnus dot com>]

This accounts for backtraces in which 'main' was called from 'start'.

2001-11-07  Michael Snyder  <msnyder@redhat.com>

	* gdb.asm/asm-source.exp (bt ALL in foo2): Accept a backtrace that
	includes a stack frame for "start".
