I've now fixed this problem by adding -notransfer to the pattern.
Tested on s390-ibm-linux, s390x-ibm-linux, and spu-elf.  Fixes
the failure on spu-elf.  Committed to mainline.

Ulrich

ChangeLog:

	* lib/gdb.exp (gdb_run_cmd): Use -notransfer to make start-up
	messages available to test cases (like chng-sym.exp).
