Right now the build system builds the host tools over and over again, in some environments especially when running in an IDE on windows for example, this is not desired and a set of pre-built host tools should be used. Provide an option to use pre-built tools instead of building them from source. To use, set PREBUILT_HOST_TOOLS to the path where all pre-built host tools are hosted. To get a prebuilt version of the host tools, build without the variable set and copy the generated host binaries from outdir. The following tools are supported: * conf * fixdep * gen_idt * gen_offset_header Jira: ZEP-237 Change-Id: Iea505bfd0b50f851ee2781b5117bb6085ab20157 Signed-off-by: Anas Nashif <anas.nashif@intel.com>
