Fix regular expression used by 'make update' to only look for 'I' and '?' at the start of svn info results and to check for spaces after 'I' instead of just after '?'.

Previously it was able to match 'I' anywhere in the filenames of the svn info results instead of just files that where ignored or unknown to svn. This would cause 'make update' to infinitely recurse if a file was modified with I anywhere in its name since svn info would return a Path pointing to the llvm root for those files.

Use a simple recursive bash function to search for svn repos for the 'make
update' target thus including projects like clang-tools-extra.

I also moved the SDKROOT setting into the make flags, since clearing it from
the environment isn't good enough to override a setting on the make command
line.  That hasn't been a problem but it could be, and it's good to be
consistent with the way UNIVERSAL_SDK_PATH is handled.

My previous change to install llvm-config-host for cross-builds resulted
in that file being installed even when the normal llvm-config was not
installed, e.g., when building the install-clang target.  Daniel suggested
this alternative, which solves the immediate problem and also avoids the gunk
in the top-level makefile.

Now that llvm-config is a binary instead of a script the version installed
during a cross compiled build cannot be run from the host.  When cross
compiling, install a separate llvm-config-host that will run on the host.

And fix the comment about where the FilesToConfig variable
is.

When I did this before it broke a buildbot that was testing that target, but
we've removed that buildbot now.

Removing that buildbot would be a better solution, but this is at least
a temporary workaround.

Should unbreak Clang cross build.

Also disable Polly for the native tool build, since it depends on
external libraries which may not be available, and it isn't required
anyway.

The problems that llvmc solved have largely been subsumed with the
tasks that the clang driver can accomplish, but llvmc lacks flexibility
and depends too heavily on the EOL'd llvm-gcc.

If enabled, this will attempt to use the CC_LOG_DIAGNOSTICS feature I dropped
into Clang to print a log of all the diagnostics generated during an individual
build (from the top-level). Not sure if this will actually be useful, but for
now it is handy for testing the option.
