[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=37751a97d9c8a8b35f1942228547a954f7ed9098
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This reverts commit e86af4c3961e1f30f2d48a8946a35edd95ab3ec4, which is
no longer needed now that the RISC-V gcc has been patched to define
_REENTRANT when -pthread is passed.
