Python-symengine fails to build

[Andreas Enge <andreas@enge.fr>]

Hello,

updating flint, I have also tried to compile python-symengine as a dependent
package, and notice that it fails, but actually it already failed before
with the error
   error: ‘LLVMLongDoubleVisitor’ is not a member of ‘SymEngine’; did you mean ‘LambdaDoubleVisitor’?

So I have updated symengine to its latest version 0.9.0, and python-symengine
to its latest version 0.9.2, and now the latter fails to build with the
different error message reproduced below.

Since it replaces a broken package by a more modern broken package, I still
took the liberty to push, but it would be nice if someone with knowledge of
python and/or symengine could have a look. Disabling the tests makes the
compilation succeed, but it would be nice to find a better solution...

Thanks,

Andreas
