If someone first configure build with LLVM_ENABLE_FFI=1 and then turn it
off, the build will fail in lib/ExecutionEngine/Interpreter because
Interpreter will try still to #include <ffi/ffi.h>, but there are no
include_directories(${FFI_INCLUDE_DIR}) now.

This patch unset()'s HAVE_FFI_H and HAVE_FFI_FFI_H from cache file if
LLVM_ENABLE_FFI=0. This forces CMake to update config.h.

with the contents of CMAKE_C(XX)_FLAGS too, else `llvm-config
--c(xx)flags' doesn't tell the absolute truth.

This comes from PR9603 and is based on a patch by Ryuta Suzuki!

unnecesary conditionals and introduced a new convenience function.

The problem was that the list of libraries for Clang's unit tests was
<clang libraries> <system libraries> <llvm libraries>. As the llvm
libraries references symbols defined on the system libraries, those
were reported as undefined.

Now we can remove RuntimeDyld from the LLVM_LINK_COMPONENTS of
tools/lli. CMakeLists.txt LLVM_LINK_COMPONENTS shall not differ from
its companion Makefile LINK_COMPONENTS.

Without this cmake fails at configuration when some target pass

Fixed a pair of IF expressions too.

before the main loop. This is necessary because the loop ignores the
items added to `link_components' after it is entered.

This way the build automatically regenerates the makefiles when a svn

AC_CHECK_FUNCS seeks a symbol only in libs. We should check the declaration in string.h.

FIXME: I have never seen mingw(s) have strerror_s() (not _strerror_s()).
FIXME: Autoconf/CMake may seek strerror_s() with the definition MINGW_HAS_SECURE_API in future.
