I don't set -ffunction-sections explicitly but it seems to be used when 
I look at the .cmd files. The build command is nothing fancy, I just set 
ARCH=mips CROSS_COMPILE=mips64-unknown-linux-gnuabin32- and build with 
make -j24.

I've attached the System.map, built on next-20241111 as well as it with 
this series reverted.
