Ciao Eli, 
make bootstrap fails today, I think it is due to this commit: 
commit 1c2e0615fb87727bc2aa1f871353c999b67c792a

*** You could try to:
*** - run "make extraclean" and run "make" again (or, equivalently, run
***   "make bootstrap configure=default"), to rebuild Emacs with the
***   default configuration options, which might fix the problem
*** - run "git clean -fdx" and run "make bootstrap" again, which might
***   fix the problem if "make bootstrap configure=default" did not
***   !BEWARE! "git clean -fdx" deletes all files that are not under
***   !BEWARE! version control, which means that all changes to such
***   !BEWARE! files will be lost and cannot be restored later
*** - run "make V=1", which displays the full commands invoked by make,
***   to further investigate the problem
*** - report the problem and ask for help by sending an email to
***   bug-gnu-emacs@gnu.org, mentioning at least the build error
***   message, the platform, and the repository revision displayed by
***   "git rev-parse HEAD"
