We only need libgcc for 64-bit division on RV32. Whilst GCC toolchains bundle libgcc, Clang toolchains tend not to ship libclang_rt.builtins given every compiler is a cross-compiler for every target and so you would need a silly number of builds of it, with only the native library available; only vendor-provided Clang toolchains specifically for bare metal cross-compiling are likely to provide it. Thus, import part of FreeBSD's implementation of the division support functions needed and stop linking against libgcc.
