title: What is the standalone toolchain?
body: <p>I am trying to understand what a standalone toolchain means.
  Following are my findings.
   A toolchain which is ready to use with all the configuration that is the system headers and libraries in the correct path . For Android it will also have the API headers in the path where the toolchain can look it up. Why the term "standalone"? This probably will be different that the regular toolchain in the sense that the R T will need to be configured and made ready for android use withe sysroot and libc header paths given etc.
  Please comment .</p>
  
  <p>Hmm, I was compiling for android and one process was running a script called make-standalone-toolchain.sh a standalone toolchain is created .I was going through this script to understand what this is doing. Not really good at shell scripting. But made out certain things.                                                                ""Generate a customized Android toolchain installation that includes a working sysroot. The result is something that can more easily be used as a standalone cross-compiler, e.g. to run configure and make scripts."                                                           --toolchain   arch  ndk-dir   package-dir system  platform    variables are set   Compute source sysroot
  SRC_SYSROOT="$NDK_DIR/platforms/$PLATFORM arch-$ARCH"              Copying sysroot headers and libraries... libstdc++ headers and libraries... prebuilt binaries.all into a temporary folder then a copying from Tmp dir to install
  dir creating a tar ie a package file to add the tmpdir wanted to know what exactly is happening here or a link or suggestion where to look.but ofcourse dont want to read very elaborate manuals.
