22 Do you have CONFIG_LEGACY_PTYS=y? If so, do you really need it? A
23 little over a year ago[1] I had an annoying issue for having that
24 option enabled in my kernel, with a lot of virtual ttys reported in
25 systemctl. This is a shot in the dark (I really don't know if it's
26 related to your problem), but perhaps having the LEGACY_PTYS option
27 enabled somehow depleted your available pseudo terminals (which any X
28 terminal needs to run)? I suppose screen is also out of the question
29 for the same reason.

39 I don't see how an error about pseudo terminals could affect the
40 compilation. You could also try to compile with &> to a log file, and
41 prepare a binary package instead of installing it immediately. The log
42 file actually could help to find the problem.
