Linux kernel flavours fail to build in autopkgtest

[Dimitri John Ledkov]

linux kernel flavours fail to build in autopkgest due to OOM whilst compiling mellanox drivers:

  CC [M] drivers/net/ethernet/mellanox/mlx5/core/en_rep.o

cc1: out of memory allocating 179343984 bytes after a total of 281513984 bytes
/tmp/autopkgtest.2l4HRm/build.sgP/src/scripts/Makefile.build:325: recipe for target 'drivers/net/ethernet/mellanox/mlx5/core/en_rep.o' failed
make[7]: *** [drivers/net/ethernet/mellanox/mlx5/core/en_rep.o] Error 1

and similar.

linux itself is already in big_package config, but i guess all linux-* flavours need to be added too. I'm not sure if we need to list all the flavours, or have a fuzzy match support added generically, or just to special case linux-* packages.

Example build failure https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/amd64/l/linux-aws-edge/20190404_022031_8023a@/log.gz

I think these are all the flavours we currently have, so maybe it is ok to just add all of these.

linux-aws
linux-aws-edge
linux-azure
linux-azure-edge
linux-gcp
linux-gcp-edge
linux-gke-4.15
linux-hwe
linux-hwe-edge
linux-kvm
linux-oem
linux-oem-osp1
linux-oracle
linux-raspi2
linux-snapdragon

Iain has already reviewed the first MP, so I'm deferring to him to review the second MP; assigning the bug to express that.

[Iain Lane (laney)]

That's merged now.

Please test that it does what you expect, and reopen the bug if not.
