avoid __memcat_p link failure
The kernel test robot reports a link error when the stm driver is a
loadable module on any v5.4 kernel:
> ERROR: "__memcat_p" [drivers/hwtracing/stm/stm_core.ko] undefined!
This was fixed in mainline with commit 7273ad2b08f8 ("kbuild: link
lib-y objects to vmlinux forcibly when CONFIG_MODULES=y"), which
is fairly intrusive.
Fix the v5.4 specific issue with a minimal subset of that patch,
linking only the failing object into the kernel. Kernels before v4.20
are not affected.
