Maciej W. Rozycki c363f834cf linux: Fix syscall list generation instructions
Make the instructions for syscall list generation match Makefile and
refer to `update-syscall-lists'; there has been no `update-arch-syscall'
target.  Also use single quotes around the command to stick to the ASCII
character set.

Fixes 4cf0d22305 ("Linux: Add tables with system call numbers").

# Replace <arch-syscall.h> with a file generated from kernel headers
# and <fixup-asm-unistd.h>. Both files are located via the sysdeps

#
# Update sysdeps/unix/sysv/linux/syscall-names.list with additional
# names found in the generated <arch-syscall.h> file, so that the
# global system call names list is a superset of the
# architecture-specific system call names.
#
# To bootstrap a new architecture, create an empty file in the right
# place and run `make update-syscall-lists' from the top-level of a
# configured, but not-yet-built glibc tree.
#
# --lock points to a file not replaced during the update operation, so
# that mutual exclusion is achieved.
