you could use strace (with or without option "-e open") to see
which files SDCC would have wanted to create.
Here (recent SDCC on Opensuse 10.0) SDCC opens several temporary
files in the directory /usr/tmp (instead of /tmp or /var/tmp).
I'm crossposting this to sdcc-devel because I think this
does not fit well to the Filesystem Hierarchy Standard
(which would allow mounting the /usr partition read-only)

The FHS http://www.pathname.com/fhs/pub/fhs-2.3.pdf allows for some legacy links
(on which SDCC should not rely on) in section 4.3:
"The following symbolic links to directories may be present. This possibility
is based on the need to preserve
compatibility with older systems until all implementations can be assumed to
use the /var hierarchy.
/usr/spool -> /var/spool
/usr/tmp -> /var/tmp
/usr/spool/locks -> /var/lock
Once a system no longer requires any one of the above symbolic links, the link
may be removed, if desired."
If you feel FreeBSD would be affected in general please file a feature request
or
rather a bug report about this on sourceforge?
Greetings,
Frieder
