[boost] patch for STLport debug libs without stldebug-mode

Hi!
I discovered to my dismay that the boost_thread lib that uses STLport uses 
STLport's special debug mode. I therefore prepared a patch (against 1.31.0) 
that renames the current 'debug' target to 'stldebug' and adds a new 'debug' 
target that only uses the normal debug version of STLport.

There are a few issues to discuss though:
- I'm no expert of the build-system, not even an adept. I just tried to 
understand what's going on and tried until it seemed to work. It is a little 
tested on MSVC6.
- I have no idea why the special debug-mode was introduced as default in the 
first place, I haven't found anything that tells why.
- I found a note in one of the bbuild v2 files (which I did neither use nor 
patch) saying that 'normal debug' is not supported. Again, why and why isn't 
that stated in the notes for the *-stlport toolsets?
- regex(IIRC) uses a 'd' in the resulting lib to mark debug libs and 'dd' to 
mark libs with special debug modes like STLport's. I adapted this naming 
convention when making the patch.

In case anyone wonders, I work in an environment where I just don't have the 
extra time for STLport's debug mode.

any comments welcome
