Brad King 80af3ae35d Cleanup generic compiler check macro documentation
This commit improves formatting and style of the documentation for the
general-purpose compiler check macros:

  CHECK_C_COMPILER_FLAG
  CHECK_C_SOURCE_COMPILES
  CHECK_C_SOURCE_RUNS
  CHECK_CXX_COMPILER_FLAG
  CHECK_CXX_SOURCE_COMPILES
  CHECK_CXX_SOURCE_RUNS

This sytle is more consistent with CMake command documentation.
It also looks nicer in the generated documentation text files.

Alexander Neundorf 8d5b090188 STYLE: fix documentation: the second short description discarded the first
one, but the first one was the correct one (i.e. the one which mentioned
that CheckC[XX]SourceRuns.cmake also tries to run the executable)

Alexander Neundorf bd8b733d5e ENH: use the same CMAKE_SKIP_RPATH setting in CHECK_C/CXX_SOURCE_RUNS as in
the main project. I think it doesn't make sense if a project disables
RPATH, uses CHECK_C_SOURCE_RUNS() to see if something is able to run, and
this succeeds because it has been built with RPATH, but an executable built
within the project won't be able to run since it has been built without
RPATH.

Alexander Neundorf 7beee2df48 STYLE: don't use FIND_INCLUDE_FILE() but only FIND_INCLUDE_FILES() in
FindThreads.h

BUG: improve CheckC(XX)SourceRuns.cmake so that it works with cross
compiling, the return value has to go in the cache but shouldn't overwrite
the actual return value, and it should go only in the cache if we have a
result from try_run() otherwise we won't get here again if we have a result
later on

Alexander Neundorf 8e6f6155c0 BUG: the SET( ... CACHE INTERNAL) didn't work as expected, since the
variable is already added to the cache inside cmTryRunCommand.cxx, so the
value used here was ignored. Additionally the INTERNAL made it internal,
which shouldn't be done when cross compiling, since here the user is
required to edit this variable manually e.g. using ccmake.

Alexander Neundorf eddf1cf39f ENH: improve TRY_RUN() for crosscompiling: instead of just failing, it now
creates two cache variables, one for the RUN_RESULT, one for the RUN_OUTPUT
(if required), which can be set or preset by the user. It has now also two
new arguments: RUN_OUTPUT_VARIABLE and COMPILE_OUTPUT_VARIABLE (the old
OUTPUT_VARIABLE merges both), so if only COMPILE_OUTPUT_VARIABLE is used the
run time output of the TRY_RUN is unused and the user doesn't have to care
about the output when crosscompiling. This is now used in FindThreads.cmake,
CheckC/CXXSourceRuns.cmake and TestBigEndian.cmake, which used the output
only for the logfile (compile output is still there). Test/TryCompile/ now
also tests the behaviour of OUTPUT_VARIABLE, RUN_OUTPUT_VARIABLE and
COMPILE_OUTPUT_VARIABLE.
