This doesn't work.  The machine-specific header will get installed to
$DESTDIR/usr/include/sys/fenv.h, and it will now include a non-existing
file.  We have to keep the symlink or to duplicate the file.

However, I'm not aware that we still support a development platform not
supporting symlinks.  Even WIndows supports them for ages now.
