Update R's spkg-install for building multiple spkgs in parallel

[qed777]

To build R with SAGE_PARALLEL_SPKG_BUILD="yes" on Mac OS X, we need to add, e.g.,

MAKEFLAGS=
export MAKEFLAGS

to the "make install" part of the package's spkg-install.

Please see #8306 about building spkgs in parallel. For MAKEFLAGS, see the GNU Make manual.

Positive review. It is extreamly simple, looks good and I've tested it on Solaris 10 on an old Sun Blade 2000 SPARC.

I really hope your code for building packages in parallel gets into Sage asap. It could make a huge difference to build times. I'll see if I can get some interest in pushing this up the priority list!
