Use INTERNAL_SYSCALL and INLINE_SYSCALL_ERROR_RETURN_VALUE
This patch uses INTERNAL_SYSCALL and INLINE_SYSCALL_ERROR_RETURN_VALUE
to avoid reading and writing errno directly so that we don't need to
call __x86.get_pc_thunk.reg to load PC into reg in case there is an
error.
* sysdeps/unix/sysv/linux/i386/brk.c (__brk): Use
INLINE_SYSCALL_ERROR_RETURN_VALUE.
* sysdeps/unix/sysv/linux/i386/fxstatat.c (__fxstatat):
Likewise.
* sysdeps/unix/sysv/linux/i386/setegid.c (setegid): Likewise.
* sysdeps/unix/sysv/linux/i386/seteuid.c (seteuid): Likewise.
* sysdeps/unix/sysv/linux/i386/fxstat.c (__fxstat): Use
INTERNAL_SYSCALLINTERNAL_SYSCALL and
INLINE_SYSCALL_ERROR_RETURN_VALUE.
* sysdeps/unix/sysv/linux/i386/lockf64.c (lockf64): Likewise.
* sysdeps/unix/sysv/linux/i386/lxstat.c (__lxstat): Likewise.
* sysdeps/unix/sysv/linux/i386/sigaction.c (__libc_sigaction):
Likewise.
* sysdeps/unix/sysv/linux/i386/xstat.c (__xstat): Likewise.
