This script looks like it's trying to create an unloadable section,
then allocate it to a loadable segment. If all the script is trying to
do is create a loadable NOBITS section, the NOLOAD attribute shouldn't
be necessary (or allowed). The fact that it contains nothing but
uninitialized space should be sufficient. I don't think gold does the
right thing in that case, but that ought to be the bug, not that
NOLOAD should make it work.

What does Gnu ld do if you omit NOLOAD? Do you have any history that
explains why NOLOAD was added to the script?
