Things like that are the reason Boost.Build does such a long path.  :-) 
Debug symbols vs none isn't so bad, but linking single- and
multi-threaded code could cause serious problems.

That said, you should be able to do what you want with something like this:

exe foo : foo.c ;

install bin
    : foo
    : <variant>release,<debug-symbols>off:<location>bin/release
      <variant>release,<debug-symbols>on:<location>bin/symbols
      <variant>debug:<location>bin/debug
;

The "bin" argument just has to be a unique target name within this
jamfile as far as I know.  "foo" should be replaced with the name of
your executable -- you should also be able to handle more than one
executable by separating the target names with spaces, like "foo bar".

I don't recall off the top of my head if the ",<debug-symbols>off" is
necessary.  You should be able to test it with "bjam -n debug release
release/debug-symbols=on" (add a "-d1" argument if you don't want to see
all the compile commands).
