We don't use musl on any noMMU platform today, so this certainly cannot
explain failures like:

  http://autobuild.buildroot.net/results/6cf/6cf75e08795d9ab194ce4e882c0f4858bad979c3/

(which was the first one mentioned in your commit log), since this
failure happens with uClibc.

Looking at http://autobuild.buildroot.net/?reason=ipkg-0.99.163, I see
(looking only at the failures since the beginning of 2016) :

 * Numerous failures on ARM noMMU (uClibc)
 * Two failures on m68k noMMU (uClibc)
 * An old failure on i686 due to download issue

i.e, none of the failures are caused by a musl-related build.
