MarsSeed [1] filed a deletion request for armv8l-linux-gnueabihf-glibc
[2]:
Unmaintained ARMv8 compiler toolchain package from 2017.
For the 64-bit supporting ARMv8 platform, but for kernels running in
32-bit mode.
PKGBUILD is wrongly arch=('any').
The build configuration targets the hard-coded
Linux kernel version 2.6.32.
I recommend deletion.
It is not useful to keep as is.
And only the few related toolchain packages depend on this, all of
which are similarly old and abandoned.
