Bug 113793

I sometimes csup /usr/src and /usr/ports and update my system.  But recently, I haven't been able to rebuild my system.  The end of the make output is:

---------------------

/libexec/ld-elf.so.1: ./libncurses.so.6: unsupported file layout
"/usr/src/lib/ncurses/ncurses/Makefile", line 14: warning: "egrep 'NCURSES_MAJOR[   ]*=' /usr/src/lib/ncurses/ncurses/../../../contrib/ncurses/dist.mk | sed -e 's%^[^0-9]*%%'" returned non-zero status

And a "stripped" version of my kernel config is:

I've been running `make buildworld buildkernel KERNCONF=CUSTOM` to get these results, but one enabling linux compat fails as well with the same problem.

The completel make output is 11 megs so I'm not sure how to provide access to it easily.  I've "cleaned" up my make.conf, leaving only the two perl env settings, although I doubt that would have any impact.

How-To-Repeat: Given the severity and the fact that it continually happens, and has for about a week(and I at least imagine someone with amd64 other than me is following stable), I don't know if it's reproducable outside my system.  I do have a complete userland jail(I don't recall if it's the save revision as my system) that I'd be willing to provide access too if someone wishes to try to diagnose the issue.  I have tried building in the jail but I got the same error.  I've deleted /usr/obj a few times, and /usr/src once before updating the -stable, but to no avail.
