The same thing as in:

https://forja.cenatic.es/plugins/scmgit/cgi-bin/gitweb.cgi?p=supergrub2/supergrub2.git;a=blob_plain;f=supergrub-meta-mkrescue;hb=22683e2b5fa0d65141c1be1a7487914b1d43f4dd

(which uses Debian packages) but using source code.

I see.

Any advice for the special where I want to build x86_64_efi + x86_pc 
hybrid disk?

Ok, I'll check that.

Well, as I don't want to have a separate directory for each build my 
question would be:

What is it the official commands for doing a safe cleanup?

I meant the ones that someone makes grub-mkrescue to look for the 
/usr/local/lib/grub/i386-pc/boot_hybrid.img files which I suppose are 
not found in source code but in the system (Gnu/Linux filesystem I mean).

Hope it's a bit more clear what I mean.

Thank you.
