# TODO tools from ${_target}-binutils package could be used instead
# of building temporary binutils. I couldn't get them to work easily,
# however. If You can (and have time), fix it.
# TODO There should be some switch to disable building of docs.
# It'd speed up the build + enable us to remove doxygen from depends
