Built sources always regenerated

[Braden McDaniel]

I have some sources that are generated with antlr. I have custom make
rules that generate the sources from the antlr grammar. I have tried
listing the generated sources in both BUILT_SOURCES and _DEPENDENCIES,
but the behavior is the same: the sources are regenerated every time,
regardless of whether the antlr grammar has been modified.

How can I keep this stuff from being regenerated all the time?
