Summary: unixccompiler.py should deal with env in linker

Initial Comment:
When the linker command begins with env, plus some environment 
settings, and when the target is c++, the modified linker command 
should place the c++ command in the proper place, which is not the 
first element of the linker array.

The following seems to be fix the problem:

I was trying to build wxPython on Mac OS X.  Without the change, it would 
compile all .c files, then when it tried to link, it would execute a command that 
looked like:

g++ MACOSX_DEPLOYMENT_TARGET=10.3 c++ ...

and fail.  This is because it overwrote "env" with "g++".  It needs to skip the 
env and its arguments, and replace (in this case) the c++.

Can you please give a specific example of what you did, what
you expected to happen, and what happened instead (precise
error messages, etc)?
