[PATCH] user-specified temporary directory for deb-pkg

["Frank A. Kingswood" <frank@kingswood-consulting.co.uk>]

Hi,

The Debian package build can be very slow when running against a slow 
NFS server. This patch allows the user to set the BUILDTMP environment 
variable to move these temporaries somewhere local.
