Could you track down a bit more precisely what is going on, i.e which
upstream commit broke this? I don't immediately see something relevant.
6501696dd7669b3d20d69beffc508c46f0a807da was already in v3.7.3 that we
were using prior to the bump in
21eca49ed5110872407b76ab9337d2877c4cda24.

Do you have some evidence that only BR2_mips64el is impacted, and not
BR2_mips64 (i.e big endian MIPS64) ?

Thanks,

Thomas
