Duplicate name of actual target when building with python and mpi support but different optimization/debug options

[dev-zero@…]

When I try to build boost with mpi and python but with "optimization=off debug-symbols=off" I get the following error:

Patch solving the issue

[Vladimir Prus]

I can confirm that

bjam release optimization=off debug-symbols=off --with-mpi

is broken in current trunk. The patch appears to be applied already. I'll investigate.
