Description Pierre Gaufillet 2016-07-30 06:54:51 UTC 
Building the kernel packages for debian on armhf with make deb-pkg fails for some configurations with error:

/usr/bin/xargs: md5sum: Argument list too long
[...]/scripts/package/Makefile:90: recipe for target 'deb-pkg' failed
make[1]: *** [deb-pkg] Error 126
Makefile:1163: recipe for target 'deb-pkg' failed
make: *** [deb-pkg] Error 2

It can be fixed in scripts/package/builddeb with something like:
