The -Ttext option was broken when used without a linker script.  It
would normally fail an assertion error.  This patch fixes it, and adds a
couple of test cases.  Committed to mainline.

	* layout.cc (Layout::relaxation_loop_body): Only clear load_seg if
	the -Ttext option is not 0 modulo the page size.  If we clear
	load_seg, clear phdr_seg too.
	* testsuite/Makefile.am (check_PROGRAMS): Add flagstest_o_ttext_1.
	(flagstest_o_ttext_1): New target.
	(check_DATA): Add flagstest_o_ttext_2.
	(flagstest_o_ttext_2): New target.
	* testsuite/Makefile.in: Rebuild.
