Issue #276 has
landed and we've merged the ansi-test branch issue-276-xoroshiro to
cmucl-expected-failures.  Thus, we can check out
cmucl-expected-failures again for running ansi-tests.

For some reason, on my Mac system, LANG isn't set and sometimes git
messages are in Korean.  So for consistency, set LANG in build.sh to a
known value that should work everywhere.

This was used to selecte whether we were building for x87 or sse2, but
we dropped support for x87 a long while ago.  Remove this var.

Add `Config.x86_linux_clang` to use clang instead of gcc to build
cmucl.  update `create-target.sh` so that it sets the motif variant
correctly when using `Config.x86_linux_clang`

See issue #68.

With this config, Fedora 28 successfully builds cmucl and passes all
the tests.

The tests create some files in /tmp.  Remove them when the test script
ends so that we get a clean directory.

I think this fixes the issue with the osx-runner sometimes failing
because it can't remove the temp files that I created locally when
testing locally.

bin/build-utils.sh:
* Temporarily turn off -batch

clx/dependent.lisp:
* WITH-ARRAY-DATA is in the LISP package, not KERNEL

clx/provide.lisp:
* For cmucl, don't compile anything else after (provide :clx)

Bootstrap files are from 21c directory instead of 21b.

Add the tests given in issue #45.

Use boot-2017-01-1.lisp to bootstrap this change  You'll still have to
use the CLOBBER-IT restart when loading new-assem in the first
build. Afterwards, it should be fine.

If -V isn't given, try to use the default, if possible.

The version must either be computed using the defaults or must be
given by the -V option.  Otherwise make-main-dist doesn't know what to
do without a version.

The positional version, arch, and os args are now commandline
switches.  This allows the user to specify arch and os names, for
example, without specifying a version.  This allows the version to be
defaulted.  Previously, the version had to be specified if arch or os
were desired.  

The original default values are used if these options aren't given.

Make motif variant default to solaris_sunc when sparc64_sunc is the
lisp variant.

When -X is given (break) just before quiting the cross-compilation.
This allows for some debugging of the cross-compiled result.

This makes it quite a bit easier to run the test suite instead of
trying to remember exactly how to invoke it from the command line.

Remove the execute bits from these files because they're not
executables.

* src/lisp/GNUMakefile
    * Don't add exec-final.o to lisp.a.  (But still remove exec-init.o
      from it.)
* src/tools/linker.sh
    * When linking the executable, need to link exec-final.o too.
* bin/make-main-dist.sh
    * Need to install exec-init.o and exec-final.o.  exec-init.o is
      needed to link a normal lisp; exec-final.o is used for the
      executable image.
    * Fix modes on some installed files.  exec-init.o, exec-final.o,
      and lisp.a don't need to be executable.

friends.

The command line args aren't relevant to lisp.
