RFR (S): 8209193: Fix aarch64-linux compilation after -Wreorder changes

[Thomas Schatzl]

Hi,

  when crosscompiling to aarch64-linux I found the following errors
caused by latest -Wreorder changes.

It would be nice if aarch64 devs could verify; I cc'ed aarch64 port dev
ml, but I do not know if this is the right list for this.

Aarch32 is probably still broken.

CR:

Webrev:

Testing:
successfully crosscompiled from amd64-linux to aarch64-linux

Thanks,
  Thomas
