Right.

There is nothing wrong in what you did. There was a bug in Buildroot,
and I already sent a patch to fix it, and the fix is part of the final
2014.05 release.

The problem was that Buildroot was assuming the pre-built Musl
toolchain was valid for both Microblaze BE and Microblaze LE, which is
not the case. Therefore, in commit
http://git.buildroot.net/buildroot/commit/?id=77ef6a3a12ec1e41317ddfa54842c6a59d75dab8
this problem was fixed. You were in Cc of the patch.

So from now on, if you select Microblaze little endian as the
architecture, the pre-built Musl toolchain will not be selectable.

Best regards,

Thomas
