Please don't be Arch-specific for the build system

[romanrm]

Hello,

Even if this builds an Arch image, it doesn't have to be that this only works on an Arch system to build.

For example I launch the scripts on a Debian machine. First attempt:

bash: ./1_compile.sh: /usr/bin/sh: bad interpreter: No such file or directory

What is wrong with the normal "/bin/sh"?

Second attempt:

./consts.sh: line 61: pacman: command not found
Please install 'riscv64-linux-gnu-gcc'

Sorry I got no "pacman" on my machine, meanwhile /usr/bin/riscv64-linux-gnu-gcc-12 is happily present and ready to be executed. Why not just check for presence of the compiler, not of an Arch package of a compiler.

Feels very petty and hostile, like "f u if you use a different distro", we will specifically hardcode our own little incompatible ways so this doesn't work on your system.

I've fixed the first error by making it distro independent.

Regarding the second, I cannot (and will not) maintain different distros, if this sounds or feels hostile, deal with it - if I remove that check, people will complain that the script isn't working because they are missing packages.
Nevertheless, I'm open for PRs, so feel free to add a check for Debian.
