* arch-utils.c (generic_cannot_extract_struct_value_address): New
function.
* arch-utils.h: Add corresponding prototype.

New variables.

(all-build-libiberty): Depend on configure-build-libiberty.
* configure: Calculate and substitute proper value for
ALL_BUILD_MODULES.
* configure.in: Create the build subdirectory.
Calculate and substitute TARGET_CONFIGARGS (formerly
CONFIG_ARGUMENTS); also BUILD_SUBDIR and BUILD_CONFIGARGS (new).
(elf64_alpha_relocate_section): Translate local_got_entries
for STT_SECTION symbol to SHF_MERGE section the first time
we see it.
* elfxx-ia64.c (struct elfNN_ia64_local_hash_entry): Add
sec_merge_done.
(get_local_sym_hash): New, extracted from get_dyn_sym_info.
(get_dyn_sym_info): Use it.
(elfNN_ia64_relocate_section): Translate local dyn entries
for STT_SECTION symbol to SHF_MERGE section the first time
we see it.
* write.c (adjust_reloc_syms): Mark SEC_MERGE symbols as used

* config/tc-sparc.c (md_apply_fix3): Likewise.
dummy frames.
(s390_frame_saved_pc_nofix): if `*fi' is a dummy frame, get the
saved PC from the dummy frame's registers.
(s390_frame_chain): Same for the saved SP.
(s390_gdbarch_init): Register `generic_save_dummy_frame_tos' as
the `SAVE_DUMMY_FRAME_TOS' method, so the dummy frame's `top' gets
set correctly.
HAVE_CONTEXT_EXTENDED_REGISTERS is defined.
* win32-nat.c: Define CONTEXT_DEBUGGER_DR that will also include extended
registers if HAVE_SSE_REGS is defined.
(mappings array): Add offset of extended registers.
(thread_rec): Use new CONTEXT_DEBUGGER_DR macro.
