             Bug #: 15118
           Summary: make tries to copy the darwin/ios compiler_rt.a even
                    though it wasn't built
           Product: Build scripts
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Makefiles

Output of make from the failing case described.

Summary: I can't build llvm + clang from svn revision 173912 because it wants
to copy tools/clang/runtime/compiler-rt/clang_darwin/ios/libcompiler_rt.a to
Debug+Asserts/lib/clang/3.3/lib/darwin/libclang_rt.ios.a, which doesn't exist.
I wasn't trying, AFAICT, to build an iOS compiler or an ARM compiler of any

Steps to reproduce:
[check out llvm r173912, then clang r173912 into tools/clang]
mkdir build && cd build
../configure --enable-targets=x86,x86_64

Expected results:
I get a compiler.

Actual results:
Build fails. The output of 'make > make.log 2>&1' is attached.

Yes, this is a regression, but I don't know the first version where it started

Notes: the attached make output is from a repeat build, not a clean build, so
it doesn't include all the compilation that went into failing at this point.
