The -Wno-implicit-function-declaration CFLAGS/patches all around are not
pretty, but they’ll vanish over time.

A wrapper would be problematic for the reason you give notably.  (In the
early days of Guix, I tried really hard to avoid compiler wrappers,
which is what Nixpkgs has, to remain as close as possible to the
toolchain and to avoid “invisible magic” afforded by wrappers.)
