I asked whether some of the system utilities and libraries are now
different from what they were before the clean install.  Because some
of those updates, and not some change in Emacs, could be the reason
for the problem you see.  For example, if you now have the latest
version of GCC, try to downgrade to the previous major GCC release,
and see if that helps.

This could mean some issue with Make or with Bash.  But it's hard to
say without seeing the full output of the build that continues.

(In general, this should be discussed on the bug tracker, not here.)

It should have been a bug report to begin with.
