Subject[PATCH] Remove the new perl dependency from build.
Date
From: Rob Landley <rob@landley.net>

Remove perl dependency introduced in 2.6.25-rc1, by shipping kernel/timeconst.h
with all the "canned" values so perl is only used to regenerate it if that
file is deleted.

Removed the special case "canned" logic from the perl script (it always requires
Math::bigint when it runs now). Moved the list of canned values into
kernel/Makefile. (It's already a selection menu in kconfig, so you can't
just feed arbitrary values into it anyway. If you add a new value to kconfig,
add it to kernel/Makefile as well and delete kernel/timeconst.h so the build
recreates it.)

I have a build system that's been happily building kernels since 2.6.16,
which can't build 2.6.25-rc1:

> TIMEC kernel/timeconst.h
> /bin/sh: perl: not found
> make[1]: *** [kernel/timeconst.h] Error 127
> make: *** [kernel] Error 2
> make: *** Waiting for unfinished jobs....

Building the kernel has never required perl before, and it's a large change to
need to build perl on x86, arm, mips, powerpc, m68k, sh4, and so on to get a
native build environment that can compile a kernel, when I didn't need to do
this for 2.6.24 or any previous version.

For the record, a self-bootstrapping system (built from linux, busybox,
uClibc, binutils, gcc, make, and bash) requires the following commands to
natively recompile everything:

At absolute paths:
/bin/bash, /bin/sh, and /lib/ld-uClinux.so.0

In $PATH:
ar, as, awk, basename, cat, cc, chmod, chown, cmp, cp, cut, date, dd, diff,
dirname, echo, egrep, env, expr, find, gcc, grep, gzip, hostname, id,
install, ld, ln, ls, make, mkdir, mktemp, mv, nm, od, patch, pwd, readlink,
rm, rmdir, sed, sha1sum, sleep, sort, tail, tar, touch, tr, true, uname,
uniq, wc, which, whoami.

(It also needs some /dev stuff and shared libraries, of course. But no
bison, no lexx, and no perl.)
