It turned out the better solution suggested by Manfred was to override
it in the t-* file.

The reason I have to do this for a specific target (that I still haven't
submitted for approval/checking) that offers an "alternate universe" of
starttups, teardowns, libraries, and headers.   Having SYSTEM_HEADER_DIR
set allows things like fixincludes to DTRT.

Setting it in the t-* file cured my problem and was cleaner than my
autoconf hack above.
