If BFD_TARG_64 is defined, set BFD_ARCH_SIZE to 64 even on 32-bit platforms.
(BFD_ARCH_SIZE is an attribute of the target, not (just) the host platform)
This is intended for building 32bit->64bit cross libbfd's (e.g.,
x86->alpha or x86->sparc64)
a BOOTSTRAP_ELF Makefile variable that, when set (e.g. in the environment),
builds a targeted-to-ELF toolchain without requiring OBJECT_FMT to be set
to "ELF" (which affects how e.g. libraries are built).
This basically means you don't need fake crtbegin.o and crtend.o files to
be present in /usr/lib while bootstrapping the toolchain.
- no includes are installed any more, nor any .a libraries
- a unified libbfd can be built if BFD_UNIFIED is set in mk.conf (will
support dumping/examining objects from all NetBSD architectures of equal
or lesser pointer size)
