summary:
gh-159914: Ignore gdb stderr in test_gdb.test_pretty_print (#159916)
test_strings() gets gdb.host_charset(), but fails if gdb writes
anything to stderr. For example, it fails if gdb logs the warning:
"/usr/bin/gdb: warning: Couldn't determine a path for the index
cache directory."
Even if stdout contains the expected encoding ("UTF-8").
Change test_gdb to only fail if stdout is empty, ignore stderr
otherwise to ignore gdb warnings.
