While compiling one of our dependent tool, a long list relocation error is showing up while linking:

SomeLibrary.a(SomeObject.o)(.text._bla_bla_bla): error: relocation overflow
collect2: error: ld returned 1 exit status
cook: command g++: exit status 1
The dependent tool is being compiled on gcc-8.x and our tool is compiled on gcc-4.x.
This problem is specifically showing up on IBM PowerPC platform, where RHEL is compiling fine.
We are being suggested to use -mcmodel=medium while compiling our code.
Could not find much help online. Any specific purpose of using this option?
                Does this answer your question? gfortran for dummies: What does mcmodel=medium do exactly?

                I'm not super familiar with PowerPC, but I assume the answer would be the same. By using -mcmodel=medium you get larger sections at the cost of some instruction density?
