weird "export"s in Makefile break old BSD make
With the 0.2.7.5 (compared to 0.2.6.*) there's a new build problem with older BSD makes. There is a bug report against pkgsrc in http://gnats.netbsd.org/50521
The problem are weird targets that have:
foo: export BAR=baz
where the export is not indented with a tab
I'm not sure what's intended here. They look like empty targets, but then what should the exports do?
micro-revision.i #export TESTING_TOR_BINARY=$(top_builddir)/src/or/tor-cov export TESTING_TOR_BINARY=$(top_builddir)/src/or/tor
and another few export lines following "FORCE:" about 10 lines below that.
Using newer BSD makes or GNU make is a workaround, but it's not clear to me what is even the intention here.
