Okay, new errors now. I've tried all of the things suggested in this
string, compiling in this manner:
$ ./configure --compiler=cc --with-gnu-make --cflags="-g
-fno-schedule-insns" --with-site-lisp=yes --debug
$ make
Lisp backtrace follows:
  # (catch #<INTERNAL EMACS BUG (opaque, size=4) 0x2fdba0> ...)
  # (unwind-protect ...)
  # (unwind-protect ...)
  kill-emacs(1)
  # bind (error debug-issue-ebola-notices)
  batch-byte-compile()

  # bind (dir file-count line end-of-options first-file-buffer file-p
  # arg tem)
  command-line-1()
  # bind (command-line-args-left)
  command-line()

  normal-top-level()
  # (condition-case ... . error)
