package/pahole: new host package

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.
