in configargs.h, as well as normalising to /usr/src, normalise the
--build to the same as the --host, so that it never changes based
upon the host you ran mknative on. (some recent changes are only
because i updated a system from netbsd-7 to netbsd-8. this will
avoid that in the future.)

also fetch GCOV_DUMP_OBJS.

pullout port_specific_symbol_files from libstdc++.

use the variable for the source dir instead of duplicating it.

revert our changes; softfloat removal is now done in libgcc/config.host

We provide our own soft-float implementation in libc, so elide the libgcc
sources for it.

set NETBSD_GCC_VERSION for GCC 5.3 separately.
don't collect crtstuff anymore.

grab insn-modes.h, and do the libgcc bootstrap from gcc as well.

- pull i386-builtin-types.inc automatically on x86
- reenable cxx rt support
- don't grab insn-modes.h, we build it
- rename the c98 and c11 subdir codecvt.cc files while extracting
them with mknat

update for GCC 5.3 libgcov and libstdc++

very first baby steps towards GCC 5.3 mknative.

add a comment saying this is for GCC 4.8

kill the -fPIC that m68000 ends up with, fixing it in the specs
is not trivial..

canonicalise the src dir to /usr/src, so it doesn't matter
where we run mknative.

Don't grab libstdc++-v3/config.h it's not used.

don't collect gthr-default.h anymore.

don't collect c++allocator.h. we copy it via G_ALLOCATOR_H we've
already pulled out, and the extra copy can confuse make when it
has an older timestamp than the copy in dist/libstdc++-v3/.

prepare for moving GCC 4.5 into gcc.old:

- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places;

prepare for moving GCC 4.5 into gcc.old:

- convert to using ${EXTERNAL_GCC_SUBDIR}
- define base-external-gpl3-gcc* subdir as GCC_SUBDIR
- use <bsd.init.mk> over <bsd.own.mk> for a bunch of places; mostly
because it arranges for ../Makefile.inc to be included earlier, and
don't bother including the latter if the former is already included.
- move all .PATH: settings after <bsd.{own,lib}.mk> so that all
valid variables are set before it is evaluated
- rename mknative-gcc* to match their subdir name.

XXX the relationship between the Makefile.inc/Makefile.gcc_path files
is kind of sketchy, it would be great if this was fixed.

The mpfr sources moved down into a src directory - deal with this in
mknative.

update to MPC 1.0.1.

Deleted 1 line too many in previous commit.

g/c gcc3 goop

pass both NEWCONFIGDIR and NETBSDSRCDIR to mknative-gcc.

Create a sanitise_includes function and use it everywhere it's needed.

Avoid populating mknative output with gmp,mpfr, and mpc source
directories
