clang-cross-canadian is just symlinking into nativesdk-clang unlike gcc which
has separate binaries and they have inbuilt dynamic linker specs. To help clang
built cross-canadian binaries add it via cmdline option here, cross-canadian
binaries are only usable on installed SDKs, and these paths get re-written with
correct SDK specific linker during SDK install relocation process.

This helps clang built cross-canadian tools e.g. from binutils-cross-canadian
be relocated correctly on SDK install.

v2: Use a placeholder that is not confusing with real ldso
