SIGSEGV on exit with unix port #539
Description
Describe the bug
When i execute the unix binary, the process seems to work fine, but throws SIGSEGV when on exit. This happens both when I run a script or when I just enter and exit REPL without any commands.
Simple repro steps:
$ build/lvgl_micropy_unix -c 'import sys; print(sys.implementation)'
(name='micropython', version=(1, 27, 0, ''), _machine='linux [GCC 15.2.1] version', _mpy=2822, _build='standard', _thread='unsafe')
fish: Job 1, 'build/lvgl_micropy_unix -c 'imp…' terminated by signal SIGSEGV (Address boundary error)
By examining gdb output, I found a workaround. It's enough to construct a machine.Timer object before the interpreter quits:
$ build/lvgl_micropy_unix -c 'import machine; machine.Timer(0); import sys; print(sys.implementation)'
(name='micropython', version=(1, 27, 0, ''), _machine='linux [GCC 15.2.1] version', _mpy=2822, _build='standard', _thread='unsafe')
As seen in the gdb output, the program crashes in machine_timer_deinit_all():
__pthread_clockjoin_ex (threadid=0, thread_return=thread_return@entry=0x0,
clockid=clockid@entry=0, abstime=abstime@entry=0x0, block=block@entry=true)

Expected behavior
The process quits without SIGSEGV.
