Subject: Add a valgrind function
X-Git-Url: https://git.llucax.com/software/makeit.git/commitdiff_plain/6f045d91850bab9b78c3283f1b2e230fd18751b4?ds=sidebyside

Add a valgrind function

The new valgrind function runs a command through valgrind if $(VALGRIND) is
non-empty. This is generally useful to use in the "test" goals.
