# This target performs two actions:
#
# Replace <arch-syscall.h> with a file generated from kernel headers
# and <fixup-asm-unistd.h>. Both files are located via the sysdeps
# override search path.
#
# 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.
