Subject: [PATCH] Prevent erroneous copying of the data section

With __data_load declared outside the .data section, lld doesn't put
__data_load and __data_start at the same address; they differ by 16
bytes. This tricks the runtime's initialization code into thinking that
it needs to copy the data section, effectively breaking it.

Issue: eng/toolchain/gnat-llvm#64
