[PATCH bpf-next 0/3] samples/bpf: Allow building as PIE

[Viktor Malik <vmalik@redhat.com>]

Hi,

when trying to build samples/bpf as PIE in Fedora, we came across
several issues, mainly related to the way compiler/linker flags are
handled in samples/bpf/Makefile. The first 2 commits in this patchset
address these issues (see commit messages for details).

At the same time, this proposes to allow passing an already built
bpftool to samples/bpf/Makefile. The reason is to remove a redundant
build step but also because I was not able to find a correct combination
of build flags to build libbpf.a for samples/bpf/bpftool/ with -fPIE.

Viktor Malik (3):
  samples/bpf: Allow building with custom CFLAGS/LDFLAGS
  samples/bpf: Fix passing LDFLAGS to libbpf
  samples/bpf: Allow building with custom bpftool
