For example, this ran forever (as it should):

Switching to non-recursive makefiles broke the 'install-html' target:
The gettext plumbing requires an 'install-html' target in po/Makefile.
This was fixed in gettext v0.19.8.1-41-ge5a008a, but packages using
older gettext need to manually patch po/Makefile.in.in.
Reported (for 'sed') and suggested fix by Eric Blake in
https://bugs.gnu.org/25690 .
* bootstrap.conf (bootstrap_epilogue): Add 'install-{html,pdf,dvi,ps}'
targets to po/Makefile.in.in (if needed).

maint: bump makeinfo --version requirement to 6.1
* bootstrap.conf: s/4.13/6.1/ as versions previous to that
generated invalid html with interspersed <span> tags that
were visible to the user. Version 6.1 is available for a
year now, and is available in most distros.

timeout: handle multiple children on solaris
* src/timeout.c (install_sigchld): A new function to
install the SIGCHLD handler using sigaction() rather
than signal(), because with the latter on solaris
the signal handler is reset to default and thus
sigsuspend() only returns for the first finished child.
