x86: Enable -fdata-sections always

We left -fdata-sections disabled for x86_64 before because we encountered
random bugs that were at that time inexplicable.

Turns out this really was just side effects of missing .bss* statements
in the linker scripts. With those fixed, we can enable data sections for all
targets.
