Linux kernel make file define to disable objtool
Looking through the kernel code I found that an entry in Makefiles to disable
objtool:
https://elixir.bootlin.com/linux/v6.8-rc7/source/scripts/Makefile.build#L212
I have tried the patch out on RHEL9 which is most affected and the patch
eliminates the warnings. Also tried on RHEL8 to verify that instrumentation
still compiled. Now making a more extensive "make installcheck" on RHEL8/9,
fedora39, and rawhide.
