Bundle .data.rel.ro. and .data.rel.ro.local. sections

Bundle .data.rel.ro. and .data.rel.ro.local. sections

.data.rel.ro(.local). sections are (local) read only data sections with
relocations.

For example:
static const struct hvm_mmio_handler *const
hvm_mmio_handlers[HVM_MMIO_HANDLER_NR] =
{
    &hpet_mmio_handler,
    &vlapic_mmio_handler,
    &vioapic_mmio_handler,
    &msixtbl_mmio_handler,
    &iommu_mmio_handler
};

Allow these sections to be bundled so that section symbols can be
replaced with normal symbols, preventing them from being needlessly
included.
