external-toolchain: better documentation, cleanup, sysroot check
* Introduce documentation for each function of ext-tool.mk, and document all parameters of the functions. * Pass SYSROOT_DIR as argument to all functions that require it, instead of computing it manually everywhere * Use $(shell) instead of backquotes * Check that the SYSROOT_DIR variable is not empty, which means that the external toolchain doesn't support --sysroot. In that case, bail out with a nice error message. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
