Yeah, just need a bit of time. Many patch sets in progress at the same
time :)

Ok, will send a patch.

Not sure if it's BR2_bfin or !MMU. What we have is:

case "${host_os}" in
  nobody_is_using_this_currently)
    AC_DEFINE(HAVE_CODEMEM_MALLOC, 1, [Use malloc to allocate code for execution])
    ;;
  mingw*|pw32*|cygwin*)
    AC_DEFINE(HAVE_CODEMEM_VIRTUALALLOC, 1, [Use VirtualAlloc to allocate code for execution])
    ;;
  linux*|darwin*|solaris*|netbsd*|freebsd*|openbsd*|kfreebsd*|dragonfly*|gnu*)
    AC_DEFINE(HAVE_CODEMEM_MMAP, 1, [Use mmap to allocate code for execution])
    ;;
  *)
    AC_ERROR([no code allocation backend])
    ;;
esac

So when the host is uclinux (such as on !MMU platforms), nothing
matches. Which seems to match the fact that it needs a proper mmap() to
operate. So I believe it's really a "depends BR2_USE_MMU" that we need
here.

Don't know :)
