If the package build-depends on libboost-context-dev, it makes the
difference between 'Build-Attempted' and 'BD-Uninstallable'.

I had a look at which architectures have Boost.Context, and found the
inclusive list is far shorter than the exclusive list (especially if
architecture wildcards are used).  Assuming bug #794622 fixes building
on x32, the following list should work for boost 1.58 (arm64 should be
added in 1.59 [1]):

any-i386 any-amd64 armel armhf mips mipsel powerpc ppc64el

Please see the attached patch (untested).
