Use consistent test for .tbss sections in ldlang.c

Browse Source 
Some places tested SEC_LOAD, others SEC_HAS_CONTENTS.

	* ldlang.c (IS_TBSS): New macro, extracted from..
	(IGNORE_SECTION): ..here.
	(lang_size_sections_1): Use IS_TBSS and IGNORE_SECTION.
	(lang_size_sections, lang_do_assignments_1): Use IS_TBSS.
