Subject: vars.am: Add GNU Make pattern rules for Sod output files.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/sod/commitdiff_plain/055797d428ee796327bd81e0406bc765cac9ef7f

vars.am: Add GNU Make pattern rules for Sod output files.

Additional dependencies in suffix rules don't work, apparently.  Non-GNU
make(1) should just see bizarre filenames which nobody cares about, so
this is a safe thing to do.
