bfd:
* acinclude.m4, aclocal.m4: move gettext-related fragments from
aclocal.m4 to acinclude.m4, so they don't get lost.
* elfcore.h: rewrite for better corefile support.
* elf.c (elfcore_*): new functions.
* elf-bfd.h (elf_obj_tdata): new structure members.
* acconfig.h, acinclude.m4, configure.in: add feature-tests for
flavor of procfs.
* aclocal.m4, config.in, configure, Makefile.in: regenerated.
include:
* common.h (NT_PSTATUS, NT_FPREGS, NT_PSINFO,
NT_LWPSTATUS,NT_LWPSINFO): added.
* internal.h (Elf_Internal_Note): new structure members.
