It appears that libc.a from glibc 2.25 does not contain a
posix_fadvise64 symbol on mips64el

# nm /usr/lib/mips64el-linux-gnuabi64/libc.a 2>/dev/null | grep posix_fadvise
posix_fadvise.o:
posix_fadvise64.o:
0000000000000000 T __posix_fadvise64_l64
0000000000000000 T posix_fadvise

I found an upstream bug about it and it has already been fixed in glibc
2.26:

Thanks,
James
