Bug#917947: mpb-dev not built on mipsel.

[Peter Michael Green]

Package: mpb
Version: 1.7.0-3

While checking why meep wasn't migrating to testing I discovered it had 
an unsatisfiable dependency on mpb-dev.

It seems that when the architecture list for mpb was set back to "any" 
the architecuture lists for other binary packages were not updated. I am 
assuming this was a mistake, if so can you fix it, if not can you tell 
me so I can file a bug against meep.
