Subject: subdirmk: Change stub force target to `run-main.mk'
X-Git-Tag: v0.6.0~274
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?p=secnet.git;a=commitdiff_plain;h=359d8b326411f7e9c2418c094a130b0db14d859f

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
