[PATCH] specify dwarf version for Solaris

[David Blaikie]

Sorry, I'm not sure I follow - what I meant is the patch needs (or should
have, unless there's a reason this isn't testable, etc) a test case in
Clang's regression suite. Probably in clang/test/CodeGen/debug-info-*

(you could try removing other targets from that conditional and see which
tests fail - that should piont you to where to add tests for this platform)
