Subject: subdirmk: stub Makefiles: filter out `all'
X-Git-Tag: subdirmk/0.3~123^2~2
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?p=subdirmk.git;a=commitdiff_plain;h=e0d1f64d4d198205ba6f451fd400d885abf0fe78

subdirmk: stub Makefiles: filter out `all'

Otherwise `make all' generates this:
  Makefile:3: target 'all' given more than once in the same rule
which is harmless but mildly irritating.
