Bug#972069: slepc64-dev: enable ARPACK support in 64-bit build

[Drew Parsons]

Package: slepc64-dev
Version: 3.14.0+dfsg1-1
Severity: normal
Control: block -1 by 972068

ARPACK support was disabled in slepc 3.14.0+dfsg1-1 since ARPACK
cannot be used with 64-bit integers. This is because a 64-bit build of
libarpack2-dev is not yet available.

Bug#972068 has been filed to request a 64-bit build of arpack.
Once this is done it will be possible to reinstate ARPACK support in
slepc64.  It may require ILP64 support in other components of the
numerical library stack (e.g. openmpi, see Bug#961108)
