change bfd amd64 ELF_MAXPAGESIZE from 1M to 4K
An amd64 clang 10 binary built with lld 10 would abort after calling
execve(2) if it had been stripped. PT_LOAD segment aligment being
changed by strip was the cause.
Changing to 4K matches lld and results in a working binary after strip.
Introducing ELF_MINPAGESIZE of 4K (which is ELF_MAXPAGESIZE if not
defined by the arch) would have also worked but we don't support large
pages in userland.
