[PATCH v4 0/4] Add cross-compilation support to eBPF samples

These patches fix issues seen when cross-compiling eBPF samples on arm64. Compared to [1], I dropped the controversial inline-asm patch and exploring other options to fix it. However these patches are a step in the right direction and I look forward to getting them into -next and the merge window.

[PATCH v4 2/4] samples/bpf: Enable cross compiler support

When cross compiling, bpf samples use HOSTCC for compiling the non-BPF part of the sample, however what we really want is to use the cross compiler to build for the cross target since that is what will load and run the BPF sample. Detect this and compile samples correctly. Acked-by: Alexei

[PATCH v4 1/4] samples/bpf: Use getppid instead of getpgrp for array map stress

When cross-compiling the bpf sample map_perf_test for aarch64, I find that __NR_getpgrp is undefined. This causes build errors. This syscall is deprecated and requires defining __ARCH_WANT_SYSCALL_DEPRECATED. To avoid having to define that, just use a different syscall (getppid) for the array map

[PATCH v4 3/4] samples/bpf: Fix pt_regs issues when cross-compiling

BPF samples fail to build when cross-compiling for ARM64 because of incorrect pt_regs param selection. This is because clang defines __x86_64__ and bpf_headers thinks we're building for x86. Since clang is building for the BPF target, it shouldn't make assumptions about what target the BPF program
