[v2,1/1] devtools: avoid installing static binaries
Checks
Commit Message
When testing compilation and checking ABI compatibility,
there is no real need of static binaries eating disks.
The static linkage of applications was already well tested,
though the static examples tested with meson were limited to "l3fwd" only.
The static build test with make is limited to "helloworld" example.
The ABI compatibility is checked on shared libraries,
and there is no need to test again on similar builds.
A new parameter is added to the function "build",
so the ABI check is enabled only for native gcc and clang shared builds,
32-bit, generic armv8 and ppc cross compilations.
In other words, it is disabled for some static builds and some Arm ones.

v2:
- separate ABI check enablement from default library
- disable ABI check in specific Arm builds

After a second thought, I think this one should be "skipABI".

No opinion on this one.
The title might need some tweak, since you also disabled the ABI check
on some ARM targets.
The rest lgtm.

Yes, you're right.
Disabling some ABI checks is a way to reduce the number
of static binaries, but it should be visible in the title.
