All other implementations (Glibc, Musl, and Linux kernel with KASLR enabled on
modern architectures like RISC-V) do this, instead of urging the compiler to
add some feature to disable all relocs.  And sorry, your implementation is not
more important than them so it's a no-go to add burdens to the compiler just
for your case.
