The default start to .text is 6G for alpha executables, so anything
less than that + reasonable room will fail for obvious reasons.

One would think that e.g. 8G would be good enough, giving 2G above
the executable for brk and shared library mapping, but... failure.
Alternately, there's some other problem with -R that needs to be
investigated.

That said, problems with ld.so erroring out with ENOMEM went away
with this patch, so...
