'RELENG_3_3_0_RELEASE'.

This commit was manufactured to restore the state of the 3.3-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

be defined (in /etc/make.conf, say) and set to the additional architectures
that need to be compiled in. So on alpha I set CROSS_TOOLS = i386.
On i386 you can't build alpha due to lack of 64-bit support on 32-bit
architectures, but that's a GNU problem.

This change relies on makefiles in the binutils sub-directories having
the extension defined in the CROSS_TOOLS, instead of those makefiles
being selected based on the host architecture.

I moved the location of that architecture specific file.

support building it for variant architectures.  It was already
becoming clear that the former structure was too rigid and didn't
scale well.

The usual sort of makefile magic arranges to .include an architecture
specific makefile "Makefile.${MACHINE_ARCH}" in each directory
where it exists.  Also, sources will be found in each subdirectory
"${MACHINE_ARCH}" that exists.  This is all taken care of automatically
by the top level "Makefile.inc0".

This all seems to work right for the i386 now.  I have also converted
those alpha pieces already present to the new schema as best I
could.

Also: change the BINDIR on the i386 to /usr/libexec/elf for "ar"
and "ranlib".  They are not object format independent enough to
put into /usr/bin.

This finishes up the binutils import.  But I am leaving it disabled
in "src/gnu/usr.bin/Makefile" for now.  It is not used by anything
yet, so I'll take this opportunity to run one more round of tests
before enabling it.
