Tests failing on 0.7 nightly

Tested on

• 64 bit julia, 64 bit host
• 32 bit julia, 64 bit host
• 32 bit julia, 32 bit host

This might be related to timholy/SnoopCompile.jl#15 which might be some sort of mundane file IO issue.

For the matched ones:

The cross-compiling one had slightly different errors (and maybe this shouldn't be expected to work anyways):
