case:
MKBFD If set to "no", disables building of libbfd, libiberty,
and all things that depend on them (binutils/gas/ld, gdb,
dbsym, mdsetimage).
MKGDB If set to "no", disables bulding of gdb.
MKGCC If set to "no", disables building of gcc and the
gcc-related libraries (libg2c, libgcc, libobjc, libstdc++).
These are useful for building platforms for which either of the following
situations are true:
(1) You have no userland from which to run toolchain2netbsd
in order to build the appropriate toolchain build framework.
(2) The platform which you are building requires a newer set
of tools than are currently in the tree (e.g. x86-64, ia64).
* Regen files with proper OS names and version numbers.
* Clean up toolchain2netbsd somewhat, to get it ready to be cross-host
compatible (more work to be done here, but it's getting closer).
* Add framework for gdbreplay and gdbserver, but hold off on enabling these
by default until low-nbsd.c is verified to work everywhere.
the target "native toolchain" if BOOTSTRAP_NEW_TOOLCHAIN is set.
This is important if you don't have any userland at all, and you're
trying to make one from which you can run toolchain2netbsd.
dist .y and .c files reversed.
1. Move the .y.c and other assorted implicit rule overrides out of Makefile.inc
and into local Makefile's. The system Makefile (bsd.sys.mk) sets up .l.c and
.y.c rules so unless these come after all inclusions they just get ignored.
2. Add @true as the command for any of the rule overrides. Otherwise make
still bails complaining about not knowing how to build the requisite .c or
.h file.
This obviously wasn't tested before as it couldn't have worked as-is.
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.

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.
