This series contains mainly fixes/improvements for cross-compilation
(also verified on native platform build), tested on arm, but intended
for any arch.
The several patches are related to llvm clang and should be out of this
series or even fixed in another way, and here just to get comments:
arm: include: asm: swab: mask rev16 instruction for clang
arm: include: asm: unified: mask .syntax unified for clang
Also, only for armv7, there is one more problem related to long and
void type sizes for 32 bits, while the BPF LLVM back end still
operates in 64 bit, but that's another story.
Smth related not only for cross-compilation and can have impact on other
archs and build environments, so might be good idea to verify it in order
to add appropriate changes, some warn options can be tuned, so comment.

samples: bpf: Makefile: use --target from cross-compile
samples: bpf: Makefile: remove target for native build
libbpf: Makefile: add C/CXX/LDFLAGS to libbpf.so and test_libpf
targets
