Ok I should have said uClibc-xtensa/uClibc-ng...

... but indeed uClibc-xtensa is already fixed.

If you look at the config file from [1] and [2], uClibc-ng is used.

BR2_UCLIBC_VERSION_STRING="1.0.2"
BR2_UCLIBC_CONFIG="package/uclibc/uClibc-ng.config"

The commit de6561f6669308e5d2297589b39a217d4c14df1c from uClibc is not
backported yet in uClibc-ng 1.0.2.

We should instead disable pthread on xtensa only with uClibc-ng.
