Bug#737803: chocolate-doom: FTBFS: race during parallel installation

[Andreas Beckmann]

Source: chocolate-doom
Version: 2.0.0-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Hi,

your package failed to build on i386 [1] with a race condition during a
parallel make install. This is caused by overriding the documentation
destination to point to the same directory (which is not a problem,
but it requires the install to be done sequentially).
I could reproduce this race on the first attempt on amd64 with
DEB_BUILD_OPTIONS=parallel=16

The fix is easy: disable parallel installation in debian/rules by
using

    dh_auto_install --max-parallel=1 -- ...
