Noticed with gcc15, so may want backporting.

Hmmm, good catch on this. I clearly need to build a libgomp 4.7 manual
and use that for reference instead of the "normal" link at
https://www.gnu.org/software/texinfo/manual/texinfo/texinfo.html
which is for the most recent release.
I think in both places the node name specified as the first argument
should be "Top" -- the reference is intended to be to the libgomp
documentation as a whole, not the specific section about the compilation
options. (And "Enabling OpenMP" is certainly the wrong reference for
enabling OpenACC.)
No need to backport beyond GCC 15, this text was only added last
December and doesn't exist in the GCC 14 and earlier manuals.
