Please hold on.
I was also wondering what to do with the "HOST" prefix.
Libraries are usually arch-dependent.
(in other words, pkg-config should return different library paths
for $(CC) and $(HOSTCC) )
You already understood this, so you added "HOST" prefix.
Please let me take time for further discussion.
I will come back to this when I get some time.
In the meantime,
a8a5cd8b472ca20e5b8fa649c43b3756867322f8
as reference info if you have not seen it.
How many distros support something like
"aarch64-linux-gnu-pkg-config" ?
Ubuntu 18.04 and 20.04 seem to support it.
I do not know for others.
