  28 # This Makefile, together with Tools.gmk, can be used to compile a set of
  29 # gcc based cross compilation, portable, self contained packages, capable
  30 # of building OpenJDK.
  31 #
  32 # In addition to the makefiles, access to Oracle Linux installation
  33 # media is required. This has been tested against Oracle Enterprise Linux
  34 # 6.4.
  35 #
  36 # By default this Makefile will build a native toolchain for the current
  37 # platform if called with something like this:
  38 #
  39 # make tars BASE_OS=OEL6
  40 #
  41 # To build the full set of crosstools for additional platforms, use a command
  42 # line looking like this:
  43 #
  44 # make TARGETS="aarch64-linux-gnu" BASE_OS=Fedora
  45 # or
  46 # make TARGETS="arm-linux-gnueabihf ppc64-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=17
  47 #
  48 # to build several devkits for a specific OS version at once.
  49 # You can find the final results under ../../build/devkit/result/<host>-to-<target>
  50 #
  51 # This is the makefile which iterates over all host and target platforms.
