[Second attempt, this time with updated mac prebuilt]
Switches default linker from -fuse-ld-bfd to
-fuse-ld=gold, and enables -Wl,--icf=safe. This
changes reduces /system/lib64/*.so text size
by about 2% for N9.

When a shared object is rebuilt, all dependent libraries and
executables are rebuilt. Such rebuild is unnecessary when there
is no interface change. With this patch, .toc files will be
generated for all .so files. The rule which generates .toc files
has ninja's restat=1 and .toc files are not changed ninja won't
rebuild dependent targets.

gcc color diagnostics stopped working when the flag was moved to
TARGET_GLOBAL_CFLAGS, as that gets overwritten by combo/select.mk. Put
it back in COMMON_GLOBAL_CFLAGS, and then let the windows build filter
it out, similar to the way clang deals with unknown flags.

The darwin version doesn't have a trailing slash. The common case is to
append a path to it:
$(HOST_TOOLCHAIN_FOR_CLANG)/lib/...
Which means we end up with two slashes.

There will only be a very small set of non-uapi headers. This is
mostly being done for the scsi headers since the kernel has not
made uapi versions of all of them.

shamu checkbuilds set USE_CLANG_PLATFORM_BUILD, which shouldn't apply to
modules built for windows. Also fix some flags that were being set
improperly.

Instead of using recursive make to change the HOST_OS when building the
windows SDK under linux, add the concept of cross-building to another
host os.

- Added GLOBAL_JAVAC_DEBUG_FLAGS and merge it to
PRIVATE_JAVACFLAGS/PRIVATE_JACK_FLAGS to get rid of
PRIVATE_JAVAC_DEBUG_FLAGS/PRIVATE_JACK_DEBUG_FLAGS.
- With Java rules out of base_rules.mk we can get rid
of java_alternative_checked_module now.

Turns out that thanks to 9d59f41776 we actually
build *all* the host libraries both 32- and 64-bit. Rather than fix the
libraries (or fixing things so we don't build stuff we don't need) right now,
let's just put _FILE_OFFSET_BITS and _LARGEFILE_SOURCE back.

This reverts commit b8dd176441.
This wasn't the problem, and mingw doesn't even use _LARGEFILE_SOURCE. The real problem (using WIN32 instead of _WIN32 in external/llvm) is fixed now.

I forgot that removing a file doesn't cause a rebuild in our lame build
system, so I hadn't actually tested my previous change.

The only things left that we're using are the Windows target version
and _FILE_OFFSET_BITS=64, and they can go in the combo .mk.
Also fix the unused Windows 64 .mk.

We still support HOST_OS=windows for the SDK host tools cross-builds, but
that's only when USE_MINGW is set when running under linux.

The transitive symbol resolving causes build breakage when a binary
has indirect dependency on the NDK library.
This matches the change made for the the aarch64 toolchain:

Now we requires Mac OS X SDK version at least 10.8.
Also removed the unnecessary sort call in getting
mac_sdk_versions_installed.
Lexical sort doesn't make sense when 10.10 is added to that list.
Actually the next makefile line makes sure we always get the first
match in $(mac_sdk_versions_supported):
mac_sdk_version := $(firstword $(filter $(mac_sdk_versions_installed),
$(mac_sdk_versions_supported)))

Normally the binaries use the exsiting $ORIGIN/../lib[64] with binaries
in the bin subdirectory;
For historical reason the binaries in the SDK package don't have a bin
subdirectory. This workaround enables them to work in the existing SDK
directory structure.
