Subject: [PATCH 1/2] Makefile: Remove '--gcc-toolchain' flag

This is not necessary anymore now that we specify '--prefix=', which
tells clang exactly where to find the GNU cross tools. This has been
verified with self compiled LLVM 10.0.1 and LLVM 13.0.0 as well as a
distribution version of LLVM 11.1.0 without binutils in the LLVM
toolchain locations.
