Many tests specify -Ttext, -Tdata, or --section-start without SECTIONS
commands. When the specified address is lower than the image base,
* In the default --ro-segment case, there will be a read-only PT_LOAD segment covering ELF header/program headers, which may cover no section (as many tests omit .rodata). This appears unusual and has non-ascending p_vaddr.
* In the --no-rosegment case, an `error: output file too large` occurs.
We will add a diagnostic (#140187) and possibly change layout. Add
--image-base to make these tests less sensitive.
