[DRE-maint] Bug#656809: ruby-ffi: FTBFS on armhf - several failing tests

[Antonio Terceiro]

Source: ruby-ffi
Severity: grave
Justification: fails to build from source

608 tests from ./spec/ffi/variadic_spec.rb fail.

The failures look like the following:

  608) Function with variadic arguments call(jjf, long_long,2211230779876286898,long_long,2211230779876286898,float,1.23456789)
     Failure/Error: Unable to find matching line from backtrace

       expected 1.23456789
            got 4.32431801513476e-103

       (compared using ==)
     # ./spec/ffi/variadic_spec.rb:76:in `verify'
     # ./spec/ffi/variadic_spec.rb:95
     # debian/ruby-tests.rb:11

The failure seems to be related to floating point numbers. All these tests pass
on armel.
