From: Tony Ambardar <tony.ambardar@xxxxxxxxx>
Object linking output data uses the default ELF_T_BYTE type for '.symtab'
section data, which disables any libelf-based translation. Explicitly set
the ELF_T_SYM type for output to restore libelf's byte-order conversion,
noting that input '.symtab' data is already correctly translated.
Fixes: faf6ed321cf6 ("libbpf: Add BPF static linker APIs")
