Ouch. A quick ktrace indicates that message is generated by mcpcom,
which might mean that icc's ipo feature links the final binary itself
without calling ldwrapper, and that means you're not going to get a
FreeBSD binary out of the link stage. If there's an option to disable
ipo, try adding that to your icc.cfg file as a quick fix.
Since it looks like mcpcom just gets its instructions from its parent
iccbin through a temp file, it should be possible to write an mcpcom
wrapper that opens the tempfile, rewrites its contents (in a manner
similar to what ldwrapper does for the ld commandline), then launches
the real mcpcom binary.
It works!
I attached quickly-written mcpcom wrapper.
Move /usr/local/intel_cc_80/bin/mcpcom to
/usr/local/intel_cc_80/bin/mcpcom.x and then copy attached mcpcom to
/usr/local/intel_cc_80/bin/

It means ldwrapper works after mcpcom.
