Bug#871322: sketch FTCBFS: uses the build architecture compiler

[Helmut Grohne]

Source: sketch
Version: 1:0.3.7-4
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

sketch fails to cross build from source, because it uses the build
architecture toolchain (as a GNU make default). Letting dh_auto_build
call make fixes that, because dh_auto_build knows how to pass cross
compilers. Then sketch executes the just-built sketch binary for
generating the documentation. That fails with -ENOEXEC of course. Then I
figured that building the documentation is irrelevant to cross building,
because it resides in an arch:all package. Thus skipping the
documentation for arch-only builds makes sketch cross build
successfully. The attached patch uses make conditional rather than
override_dh_auto_build-indep, because it needs to build sketch before
building the documentation. Please consider applying it.
