I'd suggest skipping the glibc tests for
now, and trying just the gcc tests.
In other words, edit crosstest.sh
  #--- glibc tests ---
  if true; then
and change 'true' to false.

I think the comment's first line says it pretty well:

# Use a crufty, execrable kludge to extract the commands needed to run glibc's tests.

It's not surprising that it broke.  I haven't tried
running the glibc tests for a year or two myself,
so maybe the kludge only works with older glibc's.
