Sorry, but I don't fully understand...
With your patch to gas, the unwind info for the weak functions are completely gone in the final executable (which is good).
But "readelf -u" doesn't show the "Entry_GR=..." lines for _any_ function any longer (in the final executable).
I really mean _all_ functions, weak, non-weak, standard, ...
The patch you attached only changes the start and end addresses of the symbols...?
