Hi,
I have complete LLVM toolchain and I discovered that, detection of
compiler-rt is not working in ./configure. Because it is looking for
dynamic library compiler_rt but it doesn't exist. Instead it should ask
compiler about libgcc-file-name to get correct filename. I attached patch
to fix this issue.
