The Android NDK source repository at

information for their build system.  Add an equivalent file for each
compiler/abi combination.

Brad King fa63257821 Android: Avoid interfering with common pre-existing toolchain files
Commonly used Android toolchain files that pre-date CMake upstream
support may need to be updated to work with our new functionality.
They typically set CMAKE_SYSTEM_VERSION to 1, so detect that and
skip our upstream Android settings.  When such toolchain files are
updated to account for our upstream support, they can then set
CMAKE_SYSTEM_VERSION to a valid Android API and get new behavior.

Brad King 6299693f8a Android: Search for NDK and standalone toolchain in more places

Brad King 5a3ed0d780 Intel: Do not use MSVC-like flags for Fortran
Teach `Modules/Platform/Windows-MSVC.cmake` not to use MSVC options
for Fortran.  We use the `__windows_compiler_msvc` for the Intel
Fortran compiler on Windows for other settings, but we do not want
the flags.

Previously this worked only because the options were later overridden
by `Modules/Platform/Windows-Intel*.cmake`, but it is cleaner to not
set the options in the first place.

Brad King 78249be29d VS: Fix regressed mapping for the cl `/Os` compiler flag
In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag.  However, this collides with a mapping we already had for
the MSVC flag of the same name.  This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).

For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.

Daniel Scharrer 896ad251de Teach find_library and find_package to search lib32 paths (#11260)
Add a ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the
``FIND_LIBRARY_USE_LIB64_PATHS`` property.  This helps find commands on
multilib systems that use ``lib32`` directories and either do not have
``lib`` symlinks or point ``lib`` to ``lib64``.

Matthew Hanna 5a21557b33 AIX,HP: Allow user to override the default runtime path (libpath)
The `CMAKE_PLATFORM_REQUIRED_RUNTIME_PATH` is used by CMake to always
append `-Wl,-blibpath:/usr/lib:/lib` to the link line.  This is needed
by default on these platforms but needs to be overridden in some use
cases (e.g. an environment in which one maintains versioned shared
libraries).  Change our logic to set this value only if it not already
set by the user, project, or toolchain file.

Brad King e888af9719 MSVC: Drop space in `/DNDEBUG` flag for consistency (#16052)
We define `NDEBUG` without a space after the `-D` option for most
compilers.  Remove the space for MSVC (and Intel Fortran) for
consistency.  The MS compiler technically does not document that
the `-D` argument may be separated from its value, though every
version to date supports it.

Jean-Christophe Fillion-Robin 63c4133b38 OS X: Use -iframework with Clang only on version >= 3.2
Since commit v3.1.0-rc1~564^2 (OS X: Use -iframework for system
framework directories, 2014-05-05) we test the version of Clang is smaller
that 3.1 to see if it supports -iframework.

Considering that "iframework" support has been added in clang@r142418
(Frontend: Support -iframework.) prior to clang 3.1, this made sense.

That said, considering that support for multiple -iframework parameters
has been added later in clang@r164607 (-iframework should allow separate
arguments. ) prior to clang 3.2, this commit updates the check to enable
framework support only if version is >= 3.2
