Hi,

it seems that some Qt packages started adding Build-Depends on ccache in 
ways that you cannot just remove it. This generally causes cross build 
failures as it is the host ccache that is being installed and cannot be 
run. It's not entirely clear why we would need ccache during package 
builds (as a non-optional component), but that's another question.

I argue that one of ccache's main goals is not to behave differently 
than the real compiler. Which compiler that is is none of ccache's 
concerns, but if the passed compiler is a cross compiler, then ccache 
dutifully cross compiles stuff as expected. Therefore, I propose marking 
it Multi-Arch: foreign. Does any of d-cross@l.d.o readers have 
objections to this reasoning?

I'm attaching a patch for your convenience.

Helmut
