Call new bfd_get_size() and verify that string table is no larger
	than the file that is supposed to contain it.
	* symfile.c (syms_from_objfile):  Only complain about configured
	NAMES_HAVE_UNDERSCORE differences between gdb and bfd if the
	current target is the default BFD target.

/* Debugging check inserted for testing elimination of NAMES_HAVE_UNDERSCORE.
Complain if the dynamic setting of NAMES_HAVE_UNDERSCORE from BFD
doesn't match the static setting from the GDB config files.
doesn't match the static setting from the GDB config files, but only
if we are using the first BFD target (the default target selected by
the same configuration that decided whether NAMES_HAVE_UNDERSCORE is
defined or not). For other targets (such as when the user sets GNUTARGET
or we are reading a "foreign" object file), it is likely that the value
of bfd_get_symbol_leading_char has no relation to the value of
NAMES_HAVE_UNDERSCORE for the target for which this gdb was built.
Hack alert: the only way to currently do this with bfd is to ask it to
produce a list of known target names and compare the first one in the
list with the one for the bfd we are using.
FIXME: Remove this check after a round of testing.
