* changed boost-jam-3.1.3.src.tar.gz to boost-jam-3.1.3.tar.bz
* Added a variable RPMARCH to Jamfile.
* remove the .tar.gz and .tar.bz2 before recreating them. gzip asks for
confirmation otherwise, bzip2 just dies.
* Get rid of hardcoded /usr/src/redhat/... as it's a) distribution-specific
and b) a user can override the build root to use.
[SVN r15916]
* jam_src/Jamfile, jam_src/boost-jam.spec, jam_src/patchlevel.h:
Updated version number to 3.1.1.
* jam_src/jam.c: Made JAM_VERSION three-element string.
* bootstrap.jam: When JAM_VERSION is 3.1.1 or more, call UPDATE
explicitly on all non-option element in the command line.
