Bug#856356: linbox FTBFS on mips/mipsel: segfault in test-charpoly

[Radovan Birdic]

Hi,

Test 'test-charpoly' fails for mips and mipsel:
https://github.com/linbox-team/linbox/issues/37

A workaround at this point could be to disable this test, please see:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=797167

Current solution for this in debian/rules file (which disables this test) does 
not work properly.

Disabling test should be done before autoreconf stage.
The test has been disabled for both mips and mipsel.
I have created and attached a patch which disables this test.
With this patch package builds successfully, without test-charpoly execution.
