Bug#848634: python-cartopy: FTBFS on *i386: test_lambert_azimuthal_equal_area fails

[Aaron M. Ucko]

Source: python-cartopy
Version: 0.14.2+dfsg1-1
Severity: important
Justification: fails to build from source

The builds of python-cartopy on i386 and the non-release architecture
hurd-i386 both failed, per the below output.  I expect the kfreebsd-i386
build will fail the same way in due course.  Could you please take a
look?  Compiling native code with -ffloat-store might help.

Thanks!
