# One regtest per sample

# work because we want to save the samples as well.
# Also, we don't want to see anylog at all, save for the elapsed time, and we
# want to save the log file in a specific place
# Furthermore, force the location where the toolchain will be installed.
# Finaly, we can't use 'make sample-name' as we need to provide default values
# if the options set has changed, but oldconfig does not like when stdin is
# not a terminal (eg. it is a pipe).
