Bug#827136: Cross-compiler packages cannot be build-depended on

[Ben Hutchings <ben@decadent.org.uk>]

Package: src:gcc-5-cross
Version: 23
Severity: normal

I am looking into making the linux source package cross-buildable in a
standard way.  This requires replacing a build-dependency of e.g.:

    gcc-5 [...] <!stage1>

with:

    gcc-5 [...] <!stage1 !cross>, gcc-5-alpha-linux-gnu:any [alpha] <!stage1 cross>, ...

Unfortunately this is still unsatisfiable since the cross-compiler
packages have 'Multi-Arch: no'.  Please change this to 'Multi-Arch:
allowed'.

Ben.
