bpf, btf: Always output invariant hit in pahole DWARF to BTF transform
[ Upstream commit 2a67a6ccb01f21b854715d86ff6432a18b97adb3 ]
When trying to compile with CONFIG_DEBUG_INFO_BTF enabled, I got this
error:
% make -s
Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make[3]: *** [vmlinux] Error 1
Compiling again without -s shows the true error (that pahole is
missing), but since this is fatal, we should show the error
unconditionally on stderr as well, not silence it using the `info`
function. With this patch:
% make -s
BTF: .tmp_vmlinux.btf: pahole (pahole) is not available
Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make[3]: *** [vmlinux] Error 1
