Add a test that verifies that when ctest -j 4 is called, at most, 4 tests
are executed at any one time.
The test works by running the same script as each of 100 tests. And then setting
up test properties for DEPENDS, RUN_SERIAL, PROCESSORS and COST in order to get
the tests to run in a semi-deterministic ordering, even in parallel. The script
writes a file, sleeps for a bit, and then deletes the file. In the meantime, it
counts files that currently exist, and emits output that triggers a test failure
if the count of files is ever greater than 4.
Prior to the commit that fixed bug #12904, this would result in a failed test
because the output of some of the tests would indicate that more than 4 tests
were running simultaneously.
Now that this issue is resolved, this test will help guarantee that it stays
resolved moving forward.
The __aarch64__ defines Aarch64, while __AARCH64EB__ defines bigendian
and __AARCH64EL__ little endian. Only little endian tested, no big
endian toolchain exists yet.

The KWSys "EncodeExecutable" and "ProcessFwd9x" executables were dropped
from KWSys along with Win9x Process support. Drop references from the
rest of the CMake build rules.
Extract upstream KWSys using the following shell commands.
$ git archive --prefix=upstream-kwsys/ 933eb822 | tar x
$ git shortlog --no-merges --abbrev=8 --format='%h %s' 3b17de34..933eb822

Note it is still possible for CTest to start more than the number of
processes specified by PARALLEL_LEVEL, but this prevents the number of
tests to start from being unbounded because of overflow.
Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions. Instead we should automatically detect the framework
directories for the active toolchain.
The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories. It displays a block such as:
Framework search paths:
/...
Parse this block to extract the list of framework directories.
Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers. Always treat the paths
<sdk>/Library/Frameworks
<sdk>/System/Library/Frameworks
<sdk>/Network/Library/Frameworks # Older OS X only
/System/Library/Frameworks
as implicit. Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.
We detect the implicit link directories for the toolchain by adding a
flag to get verbose output from the compiler front-end while linking the
ABI detection binary. Newer OS X toolchains based on Clang do not add
the implicit link directories with -L options to their internal
invocation of "ld". Instead they use a linker that comes with the
toolchain and is already configured with the proper directories.
Add the "-Wl,-v" option to ask "ld" to print its implicit directories.
It displays them in a block such as:
Library search paths:
/...
Parse this block to extract the implicit link directories.
While at it, remove the checks introduced by commit efaf335b (Skip
implicit link information on Xcode, 2009-07-23) and commit 5195a664
(Skip implicit link info for multiple OS X archs, 2009-09-22). Discard
the non-system link directories added by Xcode. Discard all detected
implicit libraries in the multi-architecture case but keep the
directories. The directories are still useful without the libraries
just to suppress addition of explicit -L options for them.
Refactoring in commit 8d674e78 (Ninja: move -LIBPATH behind -link
option, 2012-09-26) accidentally added code that overwrites the
framework search path flags on each iteration instead of appending.
Change '=' to '+=' to fix it. This affects Makefile and Ninja
generators.
Extend documentation for CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES to
explain how it is used by CMake and how it can be influenced by
environment variables.
