From Rafal's commit for mipseb (which applies here too):
WARNING: Binutils 2.11.2 (maybe earlier) changed the MIPS ABI, so any
shared libs built by this toolchain WILL NOT WORK without either a whack
to BFD to fix that or a patch to ld_elf.so to work around it. I need to
chase the binutils folks on this issue still.
changes to configuration stuff to (a) recognize `mipseb', and (b) build a
BE-default GCC on mipseb. gprof and gdb still not done.
WARNING: Binutils 2.11.2 (maybe earlier) changed the MIPS ABI, so any
shared libs built by this toolchain WILL NOT WORK without either a whack

That said, the new toolchain seems to work quite well once the ABI change
is worked around/fixed -- I'm committing from a machine running a user-
land built with the new compiler.
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)
