Fix build with gcc-9 arm-linux-gnueabi toolchain
Linux toolchains link dynamically by default, so pass -static.
gcc also adds a .note.gnu.build-id to the beginning of the file, which
messes up our reset vector when converting to a raw binary file. Passing
--build-id=none to the linker gets rid of it.
