lib: utils: Drop dependency on libgcc by importing part of FreeBSD's libquad
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.
