You guys are aware that this feature is specific to GNU install, right? BSD
install--and incidentally, Mac OS X uses BSD install--does not have this.
Congratulations: you just broke installing on Mac OS and the BSDs. I'm going
to revert this change right away.

The host platform is mips-linux-gnu. Llvm and clang built successfully but
"make install" shows the following error:

You'll notice the @apple.com in my email address right?

I actually tested this on Mac OS X. Looks like strip is only invoked for Release
builds so my default build didn't catch it annoyingly enough.

The host platform is mips-linux-gnu. Llvm and clang built successfully but
"make install" shows the following error:

Why don't you fix it for mac OS then instead of reverting the whole change?

No worries, it's always easiest to revert first. I've got a different
change coming, but I'm going to commit it in the morning.
