I think the issue is complicated by the fact the the file is called
"site-config.jam" and not "host-config.jam". If the config was for a specific
host then "/etc" would be OK. For a site config "/etc" is definitely wrong!

With this in mind my prefered location from the FHS would be
"/usr/local/share". The fact that /usr is read-only does not mean that you
cannot place configuration data there. Just the system will operate if /usr
is mount read-only.
