bug#8908: --silent doesn't silence warnings

[John David Anglin]

FAIL: boehm-gc.c/gctest.c -O2 (test for excess errors)

Similar fails:
FAIL: boehm-gc.c/leak_test.c -O2 (test for excess errors)
FAIL: boehm-gc.c/middle.c -O2 (test for excess errors)
FAIL: boehm-gc.c/thread_leak_test.c -O2 (test for excess errors)
FAIL: boehm-gc.lib/staticrootstest.c -O2 (test for excess errors)

These tests fail because of the libtool warnings which are essentially
informational.

Think either --silent should silence warnings or there should be a
separate option to do so.
