Generate appropriate pseudo asm code. * sysdeps/unix/syscalls.list: Mark getgid, getpid, getuid with 'E'. * sysdeps/unix/sysv/linux/syscalls.list: Mark getegid, geteuid, getpgrp, and getppid with 'E'. * sysdeps/powerpc/powerpc32/sysdep.h: Define PSEUDO_NOERRNO, PSEUDO_END_NOERRNO, and ret_NOERRNO. * sysdeps/powerpc/powerpc64/sysdep.h: Likewise. * sysdeps/unix/sysdep.h: Likewise. * sysdeps/unix/alpha/sysdep.h: Likewise. * sysdeps/unix/sparc/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/arm/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/cris/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise.
