x86: Run PR ld/19636 tests with -z dynamic-undefined-weak

"-z dynamic-undefined-weak" makes undefined weak symbols dynamic, but
undefined weak symbols are still resolved to 0 at link-time if there
is no dynamic linker in executable.

	* testsuite/ld-i386/i386.exp: Run pr19636-1j, pr19636-1k,
	pr19636-1l, pr19636-3h and pr19636-3i.
