Consolidate Linux write syscall
This patch consolidates the write Linux syscall implementation on sysdeps/unix/sysv/linux/write.c. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * include/unistd.h (write): Add hidden proto. * io/Makefile (CFLAGS-write.c): New rule. * nptl/Makefile (CFLAGS-write.c): Likewise. * sysdeps/unix/sysv/linux/write.c: New file.
