Build error unix port and a fix

[shariltumin]

Just sharing!

It can be useful to have a unix port of MicrpPython running on your PC.

Today, I had a problem building on my PC "Linux kaki5 5.15.0-139-generic 149~20.04.1-Ubuntu"

I got this build error:

...
  File "/home/sharil/MP/20251113/micropython/tools/mpy-tool.py", line 1260, in read_obj
    obj = str_cons(buf, "utf8")
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xed in position 3: invalid continuation byte

make: *** [../../py/mkrules.mk:231: build-standard/frozen_content.c] Error 1

I don't know why this happened. I was able to build it without any problems before. One simple solution that worked for me was editing the mpy-tool.py, using "latin1" instead of "utf8".

...
            # obj = str_cons(buf, "utf8")
            obj = str_cons(buf, "latin1")
...

My variants/manifest.py includes nearly everything and some of my own stuff.

It is nice to have sqlite3.
