[PATCH] Makefiles: workaround address-of-packed-member warnings with gcc-9

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Currently fwts uses a lot of packed structures and taking the address of
members of a packed struct is throwing up a lot of warnings with gcc-9.
For the moment, let's disable this with -Wno-address-of-packed-member and
fix this up for the next release in March.
