[Buildroot] [PATCH v2 1/2] package/pahole: new host package

[Francis Laniel]

pahole is a tool used to show data structure embedded in debugging information
formats like DWARF.
It is notably needed by the Linux kernel to generate BPF Type Format (BTF)
information used by Compile Once - Run Everywhere (CO-RE) BPF tools.

To be built, pahole needs __LIB to be set to lib at stated in its README.
