 From "make[2]: *** [Makefile:129: ../nspr/out/config.status] Error 1" 
it looks like this is a failure during configure of external/nss. 
workdir/UnpackedTarball/nss/nspr/out/config.log might contain a clue as 
to why it fails for you.

Always use -O.  It doesn't make any difference for failing vs. not 
failing, it just makes sure that the output from recipes that make runs 
in parallel don't all write to the same stdout/stderr in parallel.  Not 
using -O leads to garbled output, making it hard to tell which make 
target exactly failed in what way.

Those "include file" lines should be from invoking cl with /showincludes 
(which we use for dependency tracking, similar to GCC -MD).  No idea why 
they (or at least lots of them) show up on stdout/stderr for you, though.

Yes, that's a well-known issue.
