crossdev: Use libunwind and libc++ in LLVM environments
Avoid build issues on cross environments using musl and LLVM by using
libunwind and libc++ explicitly in the clang configuration. Otherwise,
clang expects GCC libunwind and libstdc++.
These flags were not set explicitly in the clang configuration, because
LLVM profiles were setting them, but that's not the case anymore[0].
