This is a consequence of ld/emulparams/elf_x86_64.sh setting
MAXPAGESIZE=0x100000.  MAXPAGESIZE sets the maximum disk and memory
page size that might be used by whatever operating system you're
using.  Demand paging of executables generally requires that
vma % pagesize == file_offset % pagesize.

If you want to save disk space you can reduce MAXPAGESIZE to a lower
value such as 0x1000, which might be the maximum currently used by
your operating system.
