Comment:
This has been a bit messed up by me, as I made some changes which assumed
we could set CFLAGS globally, but we can't.
I'd proposed using CFLAG64 to be the C compiler flag(s) needed to build a
64-bit binary, which are usually -m64, but might not be. That could be set
globally, but lets assume for now it is not.
How would something like this seem:
If [ -z "$CFLAG64" ] ; then
CFLAG64=-m64
fi
(see how I did this in #8191)
http://trac.sagemath.org/sage_trac/attachment/ticket/8191/R.patch
Then simply append $CFLAG64 to FLINT_TUNE. But remove the -m64, as we
don't need both.
Since CFLAGS and CXXFLAGS are not set in spkg-install, there is no point
exporting them. Neither is there any point in exporting CFLAG64 or
CXXFLAG64 as again they are not used by Flint.
I think '''all''' that needs to be done is to set CFLAG64 to be -m64
unless it is set to something else, then ensure that for a 64-bit build,
FLINT_TUNE gets $CFLAG64 included.
