commit: https://git.buildroot.net/buildroot/commit/?id=1e5338ed06f74ebd8c216ba504fc1dc1e1a2f76b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Sometimes buildroot fails with:
../grub-core/kern/emu/hostfs.c:20:10: fatal error: config-util.h: No such file or directory
20 | #include <config-util.h>
| ^~~~~~~~~~~~~~~
Add a patch which fixes the Makefile to correctly generate config-util.h
first.
Note: This re-adds a workaround to avoid re-running autoconf. This has
previously been used to avoid having to run the rather complex build
file generation machinery of GRUB2. See 7e64a050fb ("boot/grub2: Fix
GRUB i386-pc build with Ubuntu gcc"), but now we just need to touch
Makefile.in.

[yann.morin.1998 at free.fr:
- add comment with patch name before hook
- slightly extend commit log that we only touch Makefile.in
]
