# dependency build is automatic, relies on gcc -MM to generate.
#
# This is a bit messy. It regenerates the dependencies on each build so
# that we catch files being added and removed. There are other ways of doing
# this (e.g. per-file dependency files) but that requires more in-depth changes
# to the build system. Compile time is not an issue for us, so the
# rebuild on every make invocation isn't a problem we need to care about. Just
# do it silently so it doesn't make the build unnecessarily noisy.
