	* include/link.h (struct link_map): Add l_tls_firstbyte_offset field.
	* sysdeps/generic/dl-tls.c [TLS_TCB_AT_TP] (_dl_determine_tlsoffset):
	Fix calculation of offsets to take misalignment of first byte in
	file into account.
	* elf/dl-load.c (_dl_map_object_from_fd): Initialize
	l_tls_firstbyte_offset field.
	* elf/rtld.c (_dl_start_final, _dl_start, dl_main): Likewise.
	* elf/dl-reloc.c (_dl_allocate_static_tls): Change return type to int.
	Take l_tls_firstbyte_offset information into account.
	(CHECK_STATIS_TLS): _dl_allocate_static_tls can fail now.
	* sysdeps/generic/ldsodefs.h: Adjust _dl_allocate_static_tls prototype.
	* elf/Makefile: Add rules to build and run tst-tls14.
	* elf/tst-tls14.c: New file.
	* elf/tst-tlsmod14a.c: New file.
	* elf/tst-tlsmod14b.c: New file.
