[U-Boot] [PATCH 2/3] mkconfig: create CONFIG_ defines without relying on GNU extensions

[Jeroen Hofstee <dasuboot@myspectrum.nl>]

Hi Mike,

I took this for irony, so I triple checked:

jeroen at green-ubuntu:~$ echo config | sed -e '/=/!s/$/=1/'
config=1
jeroen at green-ubuntu:~$ echo config=2 | sed -e '/=/!s/$/=1/'
config=2

Won't work on FreeBSD since it can't quite early [afaik] (perhaps with a 
label, but gets rather ugly..)

[jeroen at blue ~]$ echo configflag | sed -e '/=/{s/=/\t/;q}' -e 's/$/\t1/'
sed: 1: "/=/{s/=/\t/;q}
": extra characters at the end of q command

Regards,
Jeroen
