cross-pi-gcc-64 fails on debian-stretch on WSL2

[Mins0o]

I was following the wiki and encountered this issue, with other version of gcc toolchains too (8.3.0, I believe).
Using sudo did not help.

I tried the same process on ubuntu on WSL2, and that didn't have any issues until this point. (It has other issue...)

This is the error I get at the last step, on Debian but not on Ubuntu.

cmake -DCMAKE_TOOLCHAIN_FILE=~/cmake-test/PI.cmake  -DCMAKE_BUILD_TYPE=Debug ..

It fails with the following output:

I don't think fix is necessary since installing Ubuntu on WSL2 is a small extra cost, but I thought it might be worth a mention for anyone who bumps into the same issue as I did.
Maybe avoid Debian WSL2 for now and stick to Ubuntu WSL2?

I don't know what debian stretch does to files. Maybe some files are moved. Or packages are installed in other directories. All in all avoid debian for now.

@Mins0o Also while cross compiling complex libraries, avoid GCC 10.3.0 and use base toolchains like GCC 8.3.0 for buster, or GCC 10.2.0 for bullseye.
