Re: [PATCH] kbuild: depmod: fallback to /boot/System.map-KERNELRELEASE

[Adrián García Casado]

Verified on Debian 12 (x86_64) with Linux 7.3.0-rc7 packaged via
'make bindeb-pkg' while installing out-of-tree VirtualBox modules
(vboxdrv, vboxnetflt, vboxnetadp).

Before this patch:
  INSTALL /lib/modules/7.3.0-rc7/misc/vboxdrv.ko
  DEPMOD  /lib/modules/7.3.0-rc7
  Warning: modules_install: missing 'System.map' file. Skipping depmod.

With this patch applied to scripts/depmod.sh:
  INSTALL /lib/modules/7.3.0-rc7/misc/vboxdrv.ko
  DEPMOD  /lib/modules/7.3.0-rc7
  (completes with 0 warnings)

And modules.dep is properly populated:
  $ grep vbox /lib/modules/7.3.0-rc7/modules.dep
  misc/vboxnetflt.ko: misc/vboxdrv.ko
  misc/vboxnetadp.ko: misc/vboxdrv.ko
  misc/vboxdrv.ko:
