#18258: procd: in uml, procd crashes with too long command lineat times (and
loops)

Same as the other procd observation, given month old procd (and latest
trunk), everything is fine. With current, some of the uml VMs crash:
procd: - ubus -
procd: - init -
[ 5.130000] procd[1]: segfault at 0 ip 0000000040e5f340 sp
0000007fbfd48908 error 4 in libuClibc-0.9.33.2.so[40e33000+50000]
procd: Rebooting as procd has crashed
procd: reboot
..
and it loops.
I noticed that the new command line parsing code uses the define
COMMAND_LINE_LENGTH (or whatever) of 512 which is retrieved from asm-
generic; however, my platform has longer command line length support
(uml=2k), and I want to use it.
(Of course, why it crashes with too long command line is another story but
debugging procd is painful so I rather not)
TL;DR: Please get it from arch-specific file (not sure which one that is),
or just hardcode 'big enough' number like it used to be (1024). There is
no really harm putting >4k (biggest one I could find on quick grep, mips
IIRC) figure there either.
