[BusyBox] [patch] Simplify the heck out of the sed newline hack.

[Rob Landley]

Okay, instead of turning the length two string "\n" into a length three string 
"\\n", why not just turn the \n into an ascii 10 in the search pattern, and 
rip out the conversion/reversion stuff on the strings we're testing against?

The following patch does that.  It fixes some bugs I encountered in the 
binutils build from the newline hackage basically screwing things up (the 
test case I posted earlier tonight), AND makes the code smaller and simpler.  
I don't think it needs to be conditional anymore (it isn't in gnu), but I 
haven't touched menuconfig.

Treat with extreme skepticism: it worked for me configuring binutils (leaving 
me with the "s/blah/blah/;$s/blah/blah/" bug that's still blocking, but as 
far as I know that's the ONLY remaining bug, and the newline matches seem to 
be working), but I'm not entirely sure what the code I'm ripping out was 
trying to accomplish, so...
