Issue: Kernel does not compile if the in-kernel debugger (DDB) is
disabled in a custom kernel.
Steps to recreate: Install the 7.9 sys release source code.
Edit /usr/src/sys/conf/GENERIC and comment out the first option (DDB)
Configure and compile as normal - will fail with the following error
when attempting to link:
root@defender /usr/sys/arch/octeon/compile/EDGE.MP> make
ld -e start -T ld.script -Ttext=0xffffffff81000000 --warn-common -nopie

If DDB is re-enabled it compiles just fine.
Sincerely,
Gabriel
