The only problem might exist if __errno_location does not return the
proper address of rltd_errno when RTLD_PRIVATE_ERRNO is defined. It
should. If it doesn't then our definition of
SYSCALL_ERRNO_HANDLER should change in that situation (away from
DEFAULT_SYSCALL_ERROR_HANDLER which is set to __errno_location).

All we want is that SYSCALL_ERRNO_HANDLER act as a function that returns
the address of an int, into which we write the syscall error value.

Read the code in:

libc/sysdeps/generic/errno-loc.c
libc/sysdeps/generic/errno.c
libc/sysdeps/unix/sysv/linux/hppa/sysdep.h

The last file defines the syscall wrappers and their usage of
SYSCALL_ERRNO_HANDLER.

c.
