Introduce a new EXPERIMENTAL feature: BARE_METAL. This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library. Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal. Move the compiler build script to its own sub-directory. Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal. Update the ARM target tuples to enable bare-metal targets. Add two ARM bare-metal samples.

Push the calculation of the tuple's kernel part down to kernel's build scripts: - update the kernel script's API with the function CT_DiKernelTupleValues - update doc accordingly (also with the architecture change, missing in the previous commit) - small clean-up in the main script, remove useless test /trunk/scripts/build/kernel/bare-metal.sh \| 5 5 0 0 +++++ /trunk/scripts/build/kernel/linux.sh \| 5 5 0 0 +++++ /trunk/scripts/crosstool.sh \| 31 13 18 0 +++++++++++++------------------ /trunk/scripts/functions \| 15 8 7 0 ++++++++------- /trunk/docs/overview.txt \| 13 9 4 0 +++++++++---- 5 files changed, 40 insertions(+), 29 deletions(-) 2008-10-23 13:45:48 +00:00			`CT_DoKernelTupleValues() {`
