Agree that setting the compiler-rt installation directory is not ideal. I
remember I ended up doing some post installation steps to make sure that
libraries were in right folder.
Regarding this patch, currently Baremetal toolchain looks for compiler-rt in a
multilib specific directory. Does that not solve the problem of finding
compiler-rt for any given arch/abi combination automatically?
