Nice little device!

Yes, the default builds were non-unicode before. ECL has now switched to
Unicode and threads by default -- though the Unicode support was all the
time there.

Again, it is not that it was not supported: it was not active by default.

The problems arise not because of an ECL component but because of a library
we use: libatomic-ops. This library is needed to implement user-space
locking routines (mutexes, message passing queues, etc) without resorting
to complex and expensive operating system calls. There are two escape
routes here:
#1 You disable support for threads, with --disable-threads at configuration
time
#2 You install libatomic-ops from Debian and use it in ECL

#1 might be the easiest one.
