Change config.h into a platform specific includer. Mac needs config.

Unfortunately Mac needs its own build config, possibly Windows does
too, so we need to create special configs per platform. Since the
nasm source also explicitly include "config/config.h" we need to
change the base config.h into one that includes the right platform
config.

This only fixes Mac for the moment, I'll send a fix for Windows
once I've tried clang-cl on my Windows machine. At present the
config-win.h file is just a copy of the Linux one.

BUG=766721

 Local Modifications:
 * Applied deterministic.diff to make nasm deterministic.
 * Modified .gitignore not to hide generated files Chromium needs.
+* Replaced config/config.h with per-platform includer.
 
 To update, have clang in your system path (from //third_party/llvm-
 build/Release+Asserts/bin) then do the following:
 
-git remote add upstream https://repo.or.cz/nasm.git
-git fetch upstream
-git merge upstream/master
-CC=clang CXX=clang++ ./autogen.sh
-CC=clang CXX=clang++ ./configure
-make perlreq
-./generate_nasm_sources.py
-git add <any new .c/.h files which show up>

+  # Revert config/config.h to the checked in version
+
+  git commit -a
+
+In the event any new config.h flags are added, you may need to regenerate the
+config.h for each platform. You may be able to just copy new flags into all
+platform configurations, but this may not always work.
+
+The mac configuration may need some additional changes depending on the current
+SDK version being targeted by Chrome; the following change was made for 10.9:
+/* #undef HAVE_FACCESSAT */
+
+TODO(dalecurtis): Seem if there's a CFLAG that can be given to configure to
+avoid it using 10.10 features while Chrome targets 10.9 SDK.
