My mistake, it does not come from NOEXPORT...

The -fpic comes from MULTI_LIBS. I have made some sleuthing around. The
problem is not solved, but it is a difference in laziness, which makes
us have CC='$(CC_FOR_TARGET)' at this point... and get it expanded with
the -fpic, whereas gmake somehow expands this earlier.
