You've gotten further than I have in tracking this down!  Good find in
pointing the finger of suspicion on the env hiding stuff.

There have been a number of folks who have encountered this problem --
including me, at one point.  I struggled with it, determined it was
ccache that was messing up, and at that point I took the easy way out
and just renamed the /usr/bin/ccache binary to get my builds running again.

Oddly enough, now ccache seems to work fine, and I can troubleshoot no
further.

Try messing about with ccache -- disable it, or clean the caches out,
and see if anything will help.  Or you can just do what I did, and
disable it by brute force (rename the hosts' ccache binary).
