@Thomas Petazzoni: Maybe we need to rebuild the arm bleeding edge toolchain used
by the autobuilders using the current glibc version (2.30).

The current prebuilt toolchain are from 06/2019 but glibc 2.30 has been released
08/2019.

There is only one internal toolchain for arm and it use uclibc-ng by default.

Maybe we can add a new internal toolchain for glibc and musl ?

Best regards,
Romain
