don't break JVM/JS builds in same project when clang isn't present

[SethTisue]

details at scala/community-build#500

note that I wasn't trying to actually compile a Scala Native based subproject here — I was just trying to run sbt in order to compile the JVM version of scalaz. but the mere presence of the Scala Native sbt plugin in projects/plugins.sbt stopped me.

can this be handled differently in the plugin...?

[SethTisue]

(scalaz is only the first of the 90 projects in the Scala community build to add Scala Native support, but I expect — and hope — that there will be more soon)

So you still want to build JVM/JS. Do you want it to fail only when running scala-native task?

[SethTisue]

right. I won't be running any scala-native tasks. but those tasks' mere existence, somewhere else in the build, shouldn't prevent me from getting other work done.

[MasseGuillaume]

Agreed. On a tangent note. Would it be possible to support the Scala-Native target in dbuild? There is only a few dependencies to add.

[MasseGuillaume]

@densh I'm fixing this right now.

[SethTisue]

Would it be possible to support the Scala-Native target in dbuild?

@MasseGuillaume I don't know. I'd suggest asking Toni about it either at lightbend-labs/dbuild#193 or in a new ticket

The fix is coming in 0.2 that's tentatively planned for next week.
