Make error usable earlier
error (and other exception-throwing functions) are callable from the
first line of captured_main, but the exception printing code will
crash if called before the first call to set_width. This commit makes
the exception printing code usable from the moment gdb_stderr is set
up.
gdb/ChangeLog:
* exceptions.c (print_flush): Protect calls to
target_terminal_ours and wrap_here.
