* Make sure all headers used by lib/System have checks
* Use "standard" autoconf checks for certain problematic headers
For PR432:
* Resurrect --with-llvmgccdir so a specific llvm-gcc/llvm-g++ installation
can be specified.

Create new variables LLVM_ON_UNIX and LLVM_ON_WIN32 so we can start getting
rid of reliance upon a symbolic link to switch implementations in lib/System

makes a viable temporary file name. This gets around the problem with lli
on Cygwin linking but not having any "C" library functions linked into it.

* Don't search a bunch of .. directories for something we'd never find,
because we don't imbed tclsh into LLVM.
* Look for various tclsh versions because some platforms don't install the
tclsh link but just have tclsh8.3 or tclsh8.4 or some such.

* Eliminate some redundancies and complexities in the script
* Provide better documentation in the script.

relaxing the tool versions, this just isn't possible. Only certain versions
work with certain other versions.

version of the configure script. This is an early commit of the automake
support so that automake support can be tested on multiple platforms. Many
additional Makefile.am need to be added to LLVM before this is of any use.
Please wait until automake support is announced on llvmdev list before
using the --with-automake option.

from the fray, so it gets noticed. This commit is made without the
corresponding configure script commit because it doesn't affect
functionality and we don't want to force everyone into another reconfigure

Hence, it should save us some recompiling after re-configures.

Instead just create a warning message that says the directory cannot be
configured because it isn't recognized. This also gets rid of a bunch of
warning messages from the auto* tools.

function, not the whole main function. This problem resulted during
conversion of scripts to the new autoconf standard. The effect was that
the mmap_file test would fail and if it does there is currently an
#ifdef'd #error that causes compilation to fail. Bad, bad, bad.

necessary to ensure that a consistent configuration is created on each
platform. Certain definitions we use (like m4/libtool.m4) require certain
versions of the tools and we can no longer be slack about this or we'll
have problems with mis-configured builds.

This is a potential version mismatch problem because this file came from
libtool 1.5.10. If you're running a different version of libtool, the
checks in this file may not be quite right. Having our own version of this
file violates the spirit of libtool and is only provided to change the name
of "libtool" to "mklib". This is done so that the name "libtool" does not
conflict with the "lib" directory when doing tab completion and your
$objdir == $srcdir.

- Use the -I parameter to aclocal to tell it where the autoconf/m4
directory is located so it can find needed autoconf functions

autoconf functions can more easily be shared across projects.

that doesn't exist either, then error out.
