Sorry, testing is not as simple as I initially thought. Mixing code compiled
with -mlong-double-64 and code compiled without is not possible.

So in order to test this on x86 gdc needs to be built from source and
phobos/drutime have to be compiled with "-mlong-double-64" as well.

Use
DFLAGS="-mlong-double-64" ./configure
DFLAGS="-mlong-double-64" make
for this.


It might be simpler to just use one of the existing ARM (cross)compilers and
test on an ARM system.
