--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
If SYS_gettid is not defined, then it is a bug in the bionic libc headers as
NR_gettid is defined in the kernel headers.

Also pthread_yield should be defined in pthread.h if it is not then it is again
a bug in bionic.

For no you can use --disable-libcilkrts as a workaround for bionic being
broken.
