[plt-scheme] building 4.2.3 on Solaris 10

I recently changed `configure' to enable large-file support by default,
but apparently that doesn't work with the Boehm collector under
Solaris. (This problem has been reported before, I think, but I have
been very slow to look into it.)

I've changed the `configure' script in a way that should fix the
problem for future releases.

As a workaround for 4.2.3, after running `configure', edit the Makefile
in <builddir>/mzscheme/gc to remove the large-file flags from the
BASEFLAGS declaration.
