/*
* Shared linker script for the minimal coreutils (tools/echo_elf.zig,
* tools/cat_elf.zig). Identical single-PT_LOAD shape to
* tools/fsh_linker.ld: one R+X LOAD at base 0, _start shim entry, no
* page-crossing PAD. echo and cat have the same link needs, so one
* script serves both rather than two byte-identical forks.
*
* Layout:
* . = 0 — start of the only LOAD segment, page-aligned.
* .text — code; the _start shim symbol lives here. e_entry is
* set from _start via ENTRY(_start).
* .rodata* — string literals (diagnostics, separators).
* .data* — comptime-emitted constants (expected zero-sized).
* .bss* — zero-initialized data (expected zero-sized; the
* coreutils keep their buffers on the user stack so
* this stays empty — a non-zero .bss would store-fault
* on first write because the LOAD is R+X).
*
* eh_frame/note/comment/dyn* are discarded — these payloads emit no
* unwind tables, and the stock LLD layout would otherwise split
* .eh_frame_hdr / .eh_frame into a leading R-only LOAD that bumps .text
* past the page-aligned base the FlashOS loader requires.
