It seems obvious to me that there should be a way to explicitly
request a build **and install** of a tool like quickbook. E.g.:

bjam gcc debug quickbook

Once installed, rules that try to use quickbook would pick up the
installed tool and not try to build a new one with any compiler
specified on the command-line. If there was no installed quickbook,
they'd just build their own copy of the tool as required. I think
this can easily be accomplished with bjam's builtin SEARCH and LOCATE
features; if it can't we should fix that. I'm not sure how amenable
the structure of BBv2 itself is, however.

Maybe it would be a good to be able to explicitly disable use of the
installed tool also, but that's less important.
