Log Message

Ensure target triple is propagated correctly to DerivedSources.make
https://bugs.webkit.org/show_bug.cgi?id=183189
<rdar://problem/37959694>

Reviewed by Dan Bernstein.

If we don't propagate the target triple, we can sometimes build with
the wrong options enabled.

* Configurations/Base.xcconfig:
Mentioning LLVM_TARGET_TRIPLE_SUFFIX here is required to get it to be available to scripts.

* DerivedSources.make:
Propagate the target triple into our compiler invocations.
