I think the problem was mostly due to Gnulib's recent changing of how it 
handles conditionally-generated directories like lib/alloca.h. I 
installed the first attached patch to try to fix this. The second patch 
is the result of running admin/merge-gnulib, and the third does a minor 
cleanup of two new Gnulib files that Emacs doesn't need.

Also, I installed the fourth attached patch to port Emacs's Git hooks to 
Git 2.35.1, the current Git version, as Emacs was relying on an 
undocumented Git feature that Git removed. (Am I the only Emacs 
developer using up-to-date Git?)
