# Eliminate use of the built-in implicit rules, and clear out the default list
# of suffixes for suffix rules. Speeds up make quite a bit. Both are needed
# for the shortest `make -d` output.
# Don't set --no-builtin-variables; some rules might stop working if you do
# (e.g. 'make clean' in testsuite/ currently relies on an implicit $RM).
