#
# This Makefile, together with Tools.gmk, can be used to compile a set of
# gcc based cross compilation, portable, self contained packages, capable
# of building OpenJDK.
#
# By default this Makefile will build a native toolchain for the current
# platform if called with something like this:
#
# make tars BASE_OS=OL
#
# To build the full set of crosstools for additional platforms, use a command
# line looking like this:
#
# make TARGETS="aarch64-linux-gnu" BASE_OS=Fedora
# or
# make TARGETS="arm-linux-gnueabihf ppc64le-linux-gnu" BASE_OS=Fedora BASE_OS_VERSION=17
#
# to build several devkits for a specific OS version at once.
# You can find the final results under ../../build/devkit/result/<host>-to-<target>
#
# You may want the native toolchain to be used when compiling the cross
# compilation toolchains. To achieve this, first build the native toolchain,
# then add the bin directory from this build to the path when invoking this
# makefile again for cross compilation. Ex:
#
# PATH=$PWD/../../build/devkit/result/x86_64-linux-gnu-to-x86_64-linux-gnu/bin:$PATH \
#    make TARGETS="arm-linux-gnueabihf ppc64le-linux-gnu" BASE_OS=Fedora
#
# This is the makefile which iterates over all host and target platforms.
#
