Bug#979465: flint: FTBFS twice in a row

[Andreas Beckmann]

Source: flint
Version: 2.7.0-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Hi,

flint (at least in experimental, I haven't tried the version from sid)
fails to build twice in a row since not all build artifacts are cleaned
up after a successful build which breaks a subsequent dpkg-source call:

The libflint-2.7.0.so symlink is the culprit causing the failure.
