I recently changed GNU ld to use 0x10000 for the default base address.
This provides sufficient alignment for 64kB pages which makes the
experience for running ARM binaries on AArch64 Linux systems better
when the first page is unmapped. From that point of view I would
recommend using 0x10000 (although the current value is more aligned
than that, it merely wastes a little virtual address space)
