Fix MIPS n64 readahead (bug 21026).
As noted in bug 20126, MIPS n64 uses an incorrect implementation of readahead intended for 32-bit systems. This patch adds a syscalls.list entry to fix this. An updated version of the consolidation patch <https://sourceware.org/ml/libc-alpha/2016-09/msg00527.html> could remove this syscalls.list entry again. Tested with compilation (only) for mips64; the nature of the syscall doesn't allow for a glibc test to detect this issue. [BZ #21026] * sysdeps/unix/sysv/linux/mips/mips64/n64/syscalls.list (readahead): New syscall entry.
