Bug#620973: scotch: FTBFS on some architectures

[Adam C Powell IV]

Package: src:scotch
Version: 5.1.11.dfsg-5

Scotch is FTBFS on several architectures: i386, ia64, mipsel, sparc.

./dummysizes library.h scotch.h
./dummysizes libraryf.h scotchf.h

It builds fine on armel, hppa and s390.

This correlates with the buildds which use more than one job.  A
work-around may be to disable parallel building.
