Where is STRIP set for clang?

I'm not very familiar with this, but it looks like clang/llvm does come 
with its own strip utility, which would make this comment wrong.

On Linux, it's likely common to find the gnu binutils strip on the path 
even when trying to use clang to compile OpenJDK. Ideally we should 
setup STRIPFLAGS based on probing the strip executable that was found.
