[Bug boehm-gc/37017] Using --enable-threads=solaris breaks near end of build in boehm-gc configury

A few reasons. 

1. I test _all_ of gcc's configure options, submit bug reports and email test
results - "--enable-threads=solaris" is a valid choice.

2. There are more features on this Operating System. With Solaris it enables
Solaris threads _and_ pthreads simultaneously.

Here is a quick fix to allow the build to continue. I still need to run "make
-i check" on this:

Note: I unnecessarily added the "parallel mark" feature also.
