I'd much prefer to stick bx into some generic arm include instead.
What do you think?

the 'rem' below translates into sed /SOMETHING/d
Can you elaborate?
Except you mean DISTRO_FEATURES="ipv4"
and one of the gazillion distro-specific config snippets contain
CONFIG_IPV6=y
and that is not disabled.. About all those distro hunks have to go
anyway for they are redundant.

you said you saw an ICE with current uclibc master. Which arch and which
versions of the toolchain did you use?
FYI, i tested qemuarm, qemumips, qemuppc, qemux86 and (my local)
qemux86_64 with
PREFERRED_BINUTILS = "2.20.1" ¹)
PREFERRED_GCC_VERSION = "4.5" ²) ³)

and all of built fine for me.

¹) micro.conf incorrectly picks 2.19.51 per default, should be bumped
²) micro.conf should also default to 4.5
³) It would be great if we could settle on one scheme for
   binutils/gcc/libc version shorthands:
   PREFERRED_BINUTILS_VERSION _or_ PREFERRED_GCC, i'd go for
   PREFERRED_foo_VERSION, uniformly.
