In commit 97bca2f9fa (Android: Use unified toolchain in NDK r19+,
2019-07-26, v3.16.0-rc1~342^2) we hard-coded use of the unified
toolchain for NDK r19+ and skipped most of the old detection logic.
However, in that fast path we left out setting `_CMAKE_TOOLCHAIN_PREFIX`
for `CMakeFindBinutils` to select the matching binutils. Add it.
Fixes: #20038
In commit 0f150b69d3 (AIX: Explicitly compute shared object exports for
both XL and GNU, 2019-07-11, v3.16.0-rc1~418^2~2) we dropped use of the
old `CMAKE_XL_CreateExportList` cache entry for XL exports. However,
some people were setting the value to an empty string as a way to
disable automatic export of symbols. Restore this behavior when the
option is explicitly set to an empty string.
Issue: #20290
In commit fb3370b6a1 (MSVC: Add abstraction for runtime library
selection, 2019-04-10, v3.15.0-rc1~229^2) we overlooked populating the
runtime library selection flags for the Microsoft assembler. It does
not actually have any such flags, but since its compiler id is `MSVC`
our generators expect the table to be populated. Use empty values.
Without this fix, enabling the `ASM_MASM` language with policy `CMP0091`
set to `NEW` causes an error due to the missing table entries.
Fixes: #20236, #19453
Before this modification, the c_mexapi_version.c file was added to
all mex libraries. However, if the C language was not enabled
in the CMake project configuration, the c_mexapi_version.c file
was ignored, creating linking errors in Windows and macOS.
This commit ensures that in the case only the CXX languages is enabled,
the correct version is passed.

Extend the logic from commit abe8a623d9 (GNUtoMS: Add search path for VS
2017 environment scripts, 2017-05-19, v3.8.2~1^2) to consider VS 2019
paths too.

Fix the condition added by commit 68dcbeee01 (FindLAPACK: Test for
implicitly linked LAPACK libraries, 2019-06-11, v3.16.0-rc1~560^2) to
use BLAS libraries if they are sufficient with no dedicated LAPACK
libraries.
Fixes: #20099
The check added by commit 276b56f01c (FindBLAS: Add second try for
OpenBLAS with thread libraries., 2019-06-07, v3.15.0-rc2~5^2) can
work only when C or CXX is enabled.

The fix in commit 5117389931 (VS: Fix support for v142 toolset minor
versions, 2019-10-01, v3.16.0-rc1~32^2) worked around a bug in VS's
placement of toolset files. VS 16.5 will fix that bug and restore the
original pattern for locations of toolset files. Update our logic to
look for both possibilities.

Revert commit de5f123d3a (FindThreads: Do not hard-code '-l' flag on
library name, 2019-09-23, v3.16.0-rc1~71^2). Some clients depend
on the value of `CMAKE_THREAD_LIBS_INIT` to contain a valid flag.
