Subject: subdirmk: Change stub force target to `run-main.mk'
X-Git-Tag: subdirmk/0.1~3
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?p=subdirmk.git;a=commitdiff_plain;h=6fce06f32c1dd21b5c2d7a142d54b7153d650574

subdirmk: Change stub force target to `run-main.mk'

This produces significantly better error messages:
  [some error from actual makefiles]
  make[1]: Leaving directory '/home/ian/wherever'
  Makefile:6: recipe for target 'run-main.mk' failed
