I've already succeeded in doing that.
It's quite interesting. With -Twin64 I can crosscompile a win64 binary 
in WSL2.

It's not. Both of them aren't needed. I've removed both packages and I 
still ended up with a working win64 binary.

This forum post, 
https://forum.lazarus.freepascal.org/index.php/topic,56114.msg417081.html#msg417081, 
proved to be the solution:

$ sudo apt install build-essential

I have a working Linux binary now.

However, in the process I came accross another issue which I thought was 
fixed 3 years ago.

$ xidel -se 'round-half-to-even("60",3)'
60.000000000000014

In addition to -Fucomponents/pascal/import/pasdblstrutils, I explicitly 
had to add -dUSE_PASDBLSTRUTILS, after I found out (after a lot of 
searching) that you silently disabled the define in 
https://github.com/benibela/internettools/commit/f91961910298bb7d99a67f10c7b3441e143f9bf9.
Why?

With -dUSE_PASDBLSTRUTILS it at least returns...

$ xidel -se 'round-half-to-even("60",3)'
60
