Unable to cross-compile netbsd

	Hello,

	I'm not sure that it is sparc64 specific but for a few days, I'm unable 
to crosscompile netbsd sparc64. build.sh tools crashes with following 
error :

cc -DHAVE_CONFIG_H -I.

	Host system is a Linux debian/testing up to date. The same source tree 
can be built without error by a virtualized NetBSD 6.0 (amd64).
