Error: s0: Error during execution of "{C:/intelfpga/20.1/quartus/../nios2eds/Nios II Command Shell.b

Hi

Before you guys create a patch, remember there are several issues, at least 3

1. Some of the building scripts is using uname-r to check the platform, this is where the big M and little m problem occur.

One example is nios2_command_shell.sh others are

2. Some scripts is not using uname -r but other ways to determinate the platform and they also get the problems with the M and m

Most notable is reading the /proc/version file, like some perl scripts which fails because of the M and m

One example is intelFPGA/20.1/nios2eds/bin/nios2-stackreport.pl

which use

open my $handle, "<", "/proc/version" || return;
my $first_line = <$handle>;
close $handle;
return ($first_line =~ /Microsoft/);

3. There is a hickup from the earlier used cygwin remains to the new wsl when it looks for "/bin/gnu/H-x86_64-pc-linux-gnu/bin" to create the build env variables.

4. Paths problem for gcc at the very bottom.

nios2-elf-gcc.exe: fatal error: cannot execute 'cc1': CreateProcess: No such file or directory

gcc can not find the cc1 executable, it is not copied to the temporary build directory structure that is on the fly created when compiling nios.
