Thanks for doing this!

Maybe, it's possible to use:

flags gcc.compile OPTIONS <link>shared : -fPIC ;

?

Okay. That's the problem to be addressed first.

It's probably deadlock caused by catching both stderr and stdout. Command 
wrote too much to stderr and got blocked. After that, TestCmd.py is blocked 
reading stdout -- but command is blocked on stderr so won't write anything to 
stdout. 

I'll try to find a way to check if that's the cause of hang.

I believe it's because on Linux, this requires -rpath-link to work. But on 
Solaris, you've removed it. I think we need

Hmm... let's postpone this test until others are fine.

So, to summarize, we've got this problems:
- library order
- -L vs -rpath-link
- -fPIC
- conditionals
- tag hangup

I hope we'll be able to solve -fPIC soon, and then I'll have to take care of 
the first ones. Not yet sure when I'll come to that, though.
