	* resolve.cc (Symbol_table::should_override): When a weak dynamic
	defintion overrides non-weak undef, remember that the original undef
	is not weak.
	* symtab.cc (Symbol_table::sized_write_global): For undef without
	an original weak binding, set binding to global in output.
	* testsuite/Makefile.am: Add new test strong_ref_weak_def.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/strong_ref_weak_def.sh: New file.
	* testsuite/strong_ref_weak_def_1.c: Ditto.
	* testsuite/strong_ref_weak_def_2.c: Ditto.
