Build packages for generic Arm architecture
The current aarch64 version of VPP package distro in cloud repository
(https://packagecloud.io/fdio/master/ubuntu), is built on a ThunderX server,
using some arch-specific options, for example, 128Byte cache line size,
T=arm64-thunderx-linuxapp-gcc, RTE_MACHINE=thunderx
The patch is trying to build package distro with aarch64 generic features,
for both binary type targets, e.g., build/build-release, and package type
targets, e.g., pkg-deb/pkg-rpm, with the generic options, e.g.,
128Byte cache line size, T=arm64-armv8a-linuxapp-gcc, RTE_MACHINE=armv8a
If end users want to build arch specific optimized image,
TARGET_PLATFORM variable could be used, as below example,
$ make build-release/pkg-deb TARGET_PLATFORM=thunderx
