MarsSeed [1] filed a deletion request for armv8l-linux-gnueabihf- linux-api-headers [2]: Unmaintained ARMv8 cross-compiler toolchain component (Linux 4.5 kernel headers) from 2017. For the 64-bit supporting ARMv8 platform, but for kernels running in 32-bit mode. I recommend deletion. It is not useful to keep as is. And almost all related toolchain packages have already been deleted from AUR, because they were similarly abandoned (all from 2017). Also, Arch Linux ARM does not support this architecture target, and e.g. the Android project explicitly chose not to support this, as it makes no mainstream practical sense to run kernel and user processes in 32-bit on ARMv8 64-bit HW.
