# on debian at the moment: builds code that doesn't work.  But older
# versions, e.g. on current debian stable, are ok.  For current debian
# the workaround is to build your own crosscompilation toolchain,
# which should put arm-elf-gcc in your path.  We'll use that if we
# find it.  Otherwise we fall back to the prc-tools-arm chain.
