[Boost-build] exelinkflags/dlllinkflags feature

When running the Boost regression tests on Windows Mobile, it is 
necessary to explicitly specify the entry point for the test executables 
to get them to link properly.  However, this entry point can only go in 
the linkflags for executables; DLLs should use their standard entry 
point.  I did not see any existing method for specifying 
'executable-only' linkflags, so I am proposing to add two new features 
to builtin.jam: exelinkflags and dlllinkflags.  As you would expect, 
exelinkflags are additional settings passed to the linker for only EXE 
targets and dlllinkflags are settings passed to the linker for only DLL 
targets.  Attached are patches showing the relatively minor proposed 
additions.  Let me know if there is any opposition to this; otherwise I 
will go ahead and check it in.

Thanks,
-Dave
