Which "Msys command-line window"?

Please, explain..

If I try

   ./Build --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32


from msys2 shell [1], it fails, obviously, as:

$ ./Build --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32

If I run the same command from MINGW64 shell [2], it fails building icu 
library

[...]     0  1 lug 13.58 icu

because the build switches to use clang++ which does not like icu code 
(something related to 128 bit float..).

So,

$ CC=x86_64-w64-mingw32-gcc CXX=x86_64-w64-mingw32-g++ ./Build 
--build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32

fixes this issue and the build continues completing the build in libs, 
utils and many things in texk. Then it breaks at

libtool: link: x86_64-w64-mingw32-g++ -g -O2 -o xetex.exe

Indeed, libicudata.a does not exist there..
