Each PT_LOAD is a *segment* with separate attributes.  There is
no guarantee that a single read() or mmap() can necessarily handle
more than one PT_LOAD at a time, although it does work in many cases.
Both execve() and dlopen() iterate over ElfXX_Phdr, processing each
PT_LOAD separately.  A boot loader must do likewise.  For instance
ELF makes no guarantee that the PT_LOAD are in ascending order by
.p_vaddr or .p_paddr.
