mk: Use CWRAPPERS_PREPEND for --sysroot.
Looks like maybe the -Wl,-rpath-link business isn't necessary after
all -- will leave this as is until I find evidence otherwise. (joerg
says it was a workaround for NetBSD toolchain parts that weren't
properly adapted to use sysroot.)
With this, revert cwrappers version dependency to what it was before.
But keep it as TOOL_DEPENDS, not BUILD_DEPENDS.
