Bootstrapping steps:

1. Modify env.sh to accept the uname output.
2. Modify header.kmk to accept and correctly configure the platform / target OS.
3. If GNU Make v3.81 or later isn't availble, build plain make:
   1. Run aclocal, autoconf and automake in src/gmake if needed.
   2. Create and enter src/gmake/obj.
   3. Run ../configure.
   4. Run make
   5. We've now got our own make binary which will be used in the next step.
4. Build kBuild using GNU Make:
   1. Run kBuild/env.sh to configure the environment properly.
   2. Go to the root.
   3. make -f Makefile.kmk
   4. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/debug/kBuild/bin/$BUILD_TARGET_ARCH.$BUILD_TARGET/ to kBuild/bin/$BUILD_TARGET_ARCH.$BUILD_TARGET/.
5. Build a release build using kmk (which should now be in the path):
   1. Run kBuild/env.sh (or continue in the shell from the previous step).
   2. Go to the root.
   3. kmk BUILD_TYPE=release
   4. Copy out/$BUILD_TARGET.$BUILD_TARGET_ARCH/release/kBuild/bin/$BUILD_TARGET_ARCH.$BUILD_TARGET/ to kBuild/bin/$BUILD_TARGET_ARCH.$BUILD_TARGET/.
6. Add and commit the changes (including the binaries).
