write toolchain files for Android.

Brad King 8a98cf6432 Honor CMAKE_*_LINKER_FLAGS[_<CONFIG>]_INIT set in toolchain files
Document these variables.

Change our convention for setting these variables from:

    set(CMAKE_EXE_LINKER_FLAGS_INIT "...")

to

    string(APPEND CMAKE_EXE_LINKER_FLAGS_INIT " ...")

so that any value previously set by a toolchain file will be used.

Brad King a66004bee0 Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files
Document these variables.

    set(CMAKE_C_FLAGS_INIT "...")

to

    string(APPEND CMAKE_C_FLAGS_INIT " ...")

so that any value previously set by a toolchain file will be used.

Automate the conversion with:

    sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
      Modules/Compiler/*.cmake Modules/Platform/*.cmake

and follow up with some manual fixes (e.g. to cases that already
meant to append).  Also revert the automated changes to contexts
that are not protected from running multiple times.

Brad King d582c23a47 try_compile: Add policy CMP0066 to honor CMAKE_<LANG>_FLAGS_<CONFIG>
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project.  Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project.  This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.

This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.

Fixes #16174.

Extend link commands by running `ldd -u -r` to detect shared
libraries that are linked but not needed.

Brad King d256ba078a try_compile: Optionally forward custom platform variables to test project
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.

Currently, CTest will not initialize any submodules within the already
checked out source tree. Add an option to do so. The use case for not
doing so is that some submodules may not be necessary for the current
test and keeping network usage down may be important.

Brad King d7e863c1c1 VS: Do not fail on Windows 10 with VS 2015 if no SDK is available (#15929)
Since commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows
10 SDK, 2015-09-30) the VS 2015 generator requires a Windows 10 SDK to
be available when CMAKE_SYSTEM_VERSION specifies Windows 10 (e.g.  when
building on a Windows 10 host).  Howewver, it is possible to install VS
2015 without any Windows 10 SDK.  Instead of failing with an error
message about the lack of a Windows 10 SDK, simply tolerate this case
and use the default Windows 8.1 SDK.  Since building for Windows Store
still requires the SDK, retain the diagnostic in that case.

Ruslan Baratov 565d080a9a Xcode: Add support for combined install on iOS
This patch solves the problem of installing both: Device and Simulator
libraries on iOS. Before only one of them was installed.

If the IOS_INSTALL_COMBINED property is set on a target, a
special install hook will be activated which builds the corresponding
target and combines both at the install location.

The original patch was contributed by Ruslan Baratov, and polished by
Gregor Jasny.

The changes in commit c96fe0b4 (cmake: Add -W options to control

warnings.  Revert the feature until it can be revised accordingly.
