 It looks as if setting ICCBASE in mk.conf and using --compiler=icc
 should be sufficient. Although since bootstrap is supposed to create
 mk.conf, and it'll need it before bootstrap finishes, I'm not sure how
 the former part is supposed to work.
 
 Is the -static-libcxa thing still required? And should the default
 ICCBASE be adjusted to something like a recent version?
 
 (The ac_cv___attribute__ thing is now definitely handled by icc.mk.)
