[build2] Freezing with MSYS2

Things are starting to make a bit more sense for me: I thought I had
used my MSYS2's MinGW compiler when building build2, but I hadn't.  I
first tried using the .sh script but it said a bunch of things weren't
declared, so then I ran the .bat script and it seemed to work, but
then it would freeze.  I thought that it used my own compiler then,
but looking back at it I've realized it used its own compiler.

Anyway, I went back to trying to get the .sh version working, and
realized the issue is that MSYS2 provides its own gcc that is not the
gcc that you install as a package.  I installed that package, and
while the .sh script still gives an undefined reference (it got
further than before), this new gcc works with the old build2 that I
had built earlier with build2's gcc.  So, my problem has been
resolved, but if you want to try to figure out more, I can still try
to help.

I did try this before I fixed it and it did run then, but build2's gcc
is older than MSYS2's gcc, so it's not the best solution.

Thanks for your help.
