Bug#885873: cypari2: please make the build reproducible

[Chris Lamb]

Source: cypari2
Version: 1.0.0-3
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that cypari2 could not be built reproducibly as it embeds the
absolute build path in the generated .pxd files.

Patch attached.
