# This relies on GNU make (for the pattern rule) but it's just a convenience
# as you can run these check-* targets with any make using:
#
#   cd tests ; make check-FOO
#
# So the pain of maintaining a huge list of target forwarding rules here isn't
# worth it.
#
# Note: We use @PERCENT@ here instead of a literal % to suppress an automake
# portability warning.
