Hello.  With a few recent changes in arm64 compiler and linker it's of
high importance to rebuild /sys/src after sysupdate in the *correct*
manner, in order to make sure the updated linker is installed before
the compiler:

	sysupdate
	cd /sys/src/cmd/7l
	mk install
	# consider yourself PITA-free

*If* you get shit like this:

	pipe: unknown relation: TBZ
	execve: unknown relation: TBZ
	execve: unknown relation: TBZ
	execve: unknown relation: TBZ
	diff_dirs: unknown relation: TBNZ
	format_group: unknown relation: TBZ
	format_group: unknown relation: TBZ
	re_search_2: unknown relation: TBZ
	main: unknown relation: TBNZ
	pipe: unknown relation: TBZ
	execve: unknown relation: TBZ
	execve: unknown relation: TBZ
	execve: unknown relation: TBZ

pick the older 7c from the [9fs dump] and put it in /arm64/bin/7c,
then proceed with the recommended steps after sysupdate.  In case you
used hjfs with zero dumps or (worse) were stupid enough to completely
disable dumps with cwfs, feel free to get the fresh linker:

	hget https://ftrv.se/_/7l > /tmp/7l
	md5sum /arm64/bin/7l # → 1b9d6aa2092be60af7d3f5c856adc112
	cat /tmp/7l > /arm64/bin/7l

I apologize for the hassle, if any. Also no refunds.
