boot/grub2: Fix GRUB i386-pc build with Ubuntu gcc Backport a patch from upstream to fix the build on certain versions of gsc, notably: Ubuntu 19.10 with gcc (Ubuntu 8.3.0-26ubuntu1~19.10) 8.3.0 Ubuntu 19.10 with gcc (Ubuntu 9.2.1-9ubuntu2) 9.2.1 20191008 The upstream patch is simply a change in the gentpl.py script, which is used to generate parts of the automake machinery, so if we just backport the upstream patch, we need to call the script to regenerate those files. However, the modified script is a python script, so we would need to add a dependency on host-python (2 or 3), which is not so nice. Furthermore, calling the script is not enough: it needs a specific set of optionss for each file it is to generate. That set of options is not static; it is constructed in the convoluted autogen.sh. Calling autogen.sh is usally not so good an idea in the Buildroot context, and indeed this fails becasue it calls to autoreconf, but without our carefuly crafted options and environment variables. There was a little light in the tunnel, in that autogen.sh can be told not to run autoreconf, by setting the environemnt variable FROM_BOOTSTRAP to an non-=empty string, but this is fraught with various other side-effects, as in that cause, autogen.sh expects to be valled by an upper sciopt, bootstrap, which is not provided in the tarball distribution... So, between all those issues, autogen, bootstrap, and a host-python (2 or 3) dependency, we choose another route: path the script *and* the one generated file affected by the change. Since that patched file is a .am file, we also patch the corresponding .in file However, we're faced with another issue: the other generated file is now older than the script, so the automake machinery will now want to re-run autoconf et al during the build step, which is still not a good idea for us. So we touch the other generated file so it is mopre recent than the script. This is still not sufficient, because the patched file also has a dependency on the generated file, so we need to touch as well.
