The top-level guides still describe retired source, QLogic, service and
kernel-support workflows. Following them can select the wrong driver,
cross-compile only part of the tree, or misstate module-signing policy.
Commit 7aade0a109 ("Makefile: Make the qla2x00t-32gbit driver
the default QLogic FC driver") made the newer tree the default.
Commit 0d3c9018af ("debian, scstadmin: Add systemd scst.service")
added the installed systemd unit.
Point source users at GitHub and kernel support at
nightly/conf/nightly.conf. Separate kernel and user-space cross builds,
follow the current service recipes, and make module acceptance depend
on the target kernel and platform policy.
The previous commit removed support for building with clang. Restore support
for building with clang without breaking cross-compilation support.
