PT_LOAD program headers and don't try to relocate PT_TLS's p_vaddr;
	it is already absolute.

	* elf/Makefile (tests): List tst-tls1 and tst-tls2 unconditionally.
	[$(build-static) = yes] (tests): Add tst-tls1-static, tst-tls2-static.
	[$(build-static) = yes] (tests-static): New variable.
	($(tests-static):%=$(objfpx)%.o)): New static pattern rule.
