Oh well, I wish I had seen this earlier.  I already had a version of this downstream in
CheriBSD as we have a CHERI-specific case of many phdrs.  I had a sysctl/tunable to control
how many pages of phdrs were allowed which defaulted to something like 4 pages worth but
could be more easily adjusted than the hardcoded constant here.  I will see if I can upstream
the sysctl at least.
