Bug#748584: ardour3 builds with too many parallel processes

[Andreas Barth]

Package: ardour3
Version: 3.5.380~dfsg-1
Severity: serious

Hi,

the package ardour3 doesn't respect parallel in DEB_BUILD_OPTIONS and
builds with as many parallel processes as there are CPUs. This is not
so helpful on a 16-core-machine which by purpose runs two buildds in
parallel with 6 core per buildd.

aba at lucatelli:~$ ps -fu buildd2 | grep cc1plus | wc -l
16
aba at lucatelli:~$ ps -fu buildd2 | grep sbuild
buildd2   4534  3316  0 15:28 ?        00:00:07 /usr/bin/perl /usr/bin/sbuild --apt-update --no-apt-upgrade --no-apt-distupgrade [...] ardour3_3.5.380~dfsg-1
ba at lucatelli:~$ grep DEB_BUILD ~buildd2/build/current-sid
DEB_BUILD_OPTIONS=parallel=6



As per policy, package should not build parallel unless indicated by
DEB_BUILD_OPTIONS, and then use that setting (or still not build
parallel). Please fix this, this hurts the buildd infrastructure.
