It’s look like you are right. By setting CC to arm-linux-gnueabihf-gcc, 
I was able to compile the package.

But it is not the job of ’dpkg-buildpackage -a<arch>’ to set the right 
compiler and other stuff? Neither the wiki, the manpage nor the 
unofficial guides found on Internet say I have to set manually the 
compiler :-/
