MarsSeed [1] filed a deletion request for gcc-11-gnueabihf-compat [2]: arch=(arm) is invalid, but also AUR is for Arch Linux, which is x86_64.
Also the package was uploaded while missing its make dependency named 'gcc-11'. Not useful to keep. Please delete. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gcc-11-gnueabihf-compat/
