Re: [jamboost] AIX dll builds

I'm not an AIX expert... but it looks like it's a toolset problem. Looking up 
the handy shared linking site:

I don't think the problem is the -l... but the -bdynamic. Most likely without 
the -bdynamic before the -l.. it doesn't know to look for lib*.so, but looks 
for lib*.a instead. Also it should not be putting the lib*.so as a regular 
link file. The reason one wants the -l to work is so that the dynamic linking, 
when the program is run, doesn't depend on the dir you are in.

I'll just change the toolset, in HEAD, and see if it improves the situation.. 
for the regression tests.
