On x86_64 the field global_data_ptr is assigned before relocation. As sections for uninitialized global data (.bss) overlap with the relocation sections (.rela) this destroys the relocation table and leads to spurious errors.
Initialization forces the global_data_ptr into a section for initialized global data (.data) which cannot overlap any .rela section.

v2 Use .data instead of .text section
