[Bug binutils/11971] New: config.status produces incompatible defines.awk and config.h

[dhoyt at llnl dot gov]

config.h was not being created correctly on my Windows 7 (x86_64) machine 
using the latest released tools from msys/mingw, causing all sorts of build 
problems. After investigating the issue, it was narrowed down to a problem 
with how config.status produces and then uses defines.awk. That awk file uses 
a regular expression that looks for lines like "#undef VALUE_HERE" to 
eventually change them to "#define VALUE_HERE 1" if configure deems it so, but 
it wasn't finding them due to mismatches from Windows-style line endings.

This patch fixes the issue in defines.awk, but I'm unsure of where it really 
needs to go (because defines.awk is created by config.status, itself created 
through configure) since I'm not an autotools expert:
