Isn't micro using eglibc?  I wouldn't have expected that you should be
seeing glibc built at all for that DISTRO.

As I said before, binutils 2.18 is not acceptable in general because
this version cannot do Thumb code.  Glibc 2.6.1 is pretty old and, if it
is incompatible with newer toolchains, I would suggest updating to a
newer version of glibc (e.g. 2.10) rather than trying to wind the
toolchain backwards.

As a last resort we could make the binutils version be
architecture-specific, and select 2.18 for i386, but I really don't
think this ought to be necessary.
