[dpdk-dev] [PATCH] ci: fix aarch64 cross compilation in GHA

[David Marchand]

Afaics, CC_FOR_BUILD is a Travis env variable.
This results in GHA aarch64 cross compilation jobs building x86
binaries.

Example in a recent job on main branch:
2021-10-28T09:51:06.4976495Z + .ci/linux-build.sh
2021-10-28T09:51:06.4985674Z + [ -n build ]
2021-10-28T09:51:06.4987636Z + [ true = true ]
2021-10-28T09:51:06.4987991Z + [  = gcc ]
2021-10-28T09:51:06.4989419Z + [  = clang ]
2021-10-28T09:51:06.4990907Z + [ false = true ]
2021-10-28T09:51:06.4991348Z + [ false = true ]
2021-10-28T09:51:06.4992846Z + [ static = static ]

This patch can't be merged right away, since build issues are now raised
in GHA.
Please ARM people, have a look.
Thanks.
