go.tools/ssa: Package.Build panics for some packages when using a binary importer

[axw]

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Run http://play.golang.org/p/JF29YmJKun

This also occurs when building archive/zip and archive/tar, among several others in the
standard library.

What is the expected output?

No output, zero return code

What do you see instead?

panic: no concrete method: func (*math/big.Int).SetInt64(x int64) *math/big.Int

goroutine 1 [running]:
