#13680: unset BZIP2 in the build process

------------------------+---------------------------------------------------
Building Sage 5.3 (and also 4.8 and 5.2) on Ubuntu 12.04 (32-bit and
64-bit) will abort during the tests for building bzip2, if the user has
set the environment variable BZIP2 -- although bzip2's man page permits
that to specify default options.
The relevant part of the log (given 'export BZIP2="-9"') reads
{{{
bzip2-1.0.6

After 'unset BZIP2' the installation runs straight through.
This was discussed on
https://groups.google.com/forum/?fromgroups=#!topic/sage-devel/GI3t5CQEz54
and Volker Braun suggested to "unset BZIP2 in the build process" (and also
that I file this ticket).
