add an installmodules=<dir> command to build.sh

re-enable the gcc 4.5 crtstuff/libgcc builders now that they work.
also build the gmp, mpfr and mpc libraries in this case.

fix the parts that build libgcc/crtstuff, etc., for GCC 4.5.

remove all the code that supported HAVE_GCC=3. mostly from chuq.

build evbppc modules in 3 different flavours:

- oea (default)
- ibm4xx
- booke

this, together with earlier machine_module[] work, should allow evbppc
platforms to use modules.

Pass down INSTALLSETS variable to installsets target. Use :Q to escape
shell meta-characters, as the variable contains a list of sets, separated
by spaces.

Pass down INSTALLSETS variable to installsets target. Use :Q to escape
shell meta-characters, as the variable contains a list of sets, separated
by spaces.

$ ./build.sh -V INSTALLSETS="base etc" install=idir

should now work as expected.

Remove the do-external-lib and do-gnu-lib targets, along with
external/lib/Makefile and crypto/external/lib/Makefile, replacing
them all with SUBDIRs directly from lib/Makefile.

Remove the do-external-lib and do-gnu-lib targets, along with
external/lib/Makefile and crypto/external/lib/Makefile, replacing
them all with SUBDIRs directly from lib/Makefile.

compat/compatsubdirs.mk becomes simpler now, as everything is built
from lib/Makefile, meaning all the libraries will now be built under
compat so update the set lists to account for that.

Centralise USE_COMPILERCRTSTUFF.

PCC might need help.

remove almost all the ability to build netbsd with an a.out target.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

Let us use MKKMOD=yes to leave the kernel modules out of the
distribution.

Build modules before rump libs so that something else can be
unwarrantedly blamed for a change.

This commit follows the style guide and is entirely non-build-tested.

add crypto/external to the build.

Make clean_METALOG in distrib/sets early in the build, to ensure that
the METALOG does not grow without bounds on multiple MKUPDATE builds.
(Previously, sanitise_METALOG in distrib/sets/Makefile used to do
something like this near the end of a build.)

Remove an explicit BUILDTARGETS do-compat-external-lib before do-build
because now src/compat/Makefile descends there and no particular
dependency on 32 bit compat external libs during do-build.

Disable grep host tool and unbreak NetBSD build until I can come up with a
clean fix.

Use awk and grep host tools where required. 'build.sh release' now works
on Solaris (but only with HOST_CC=/usr/sfw/bin/gcc for now).
