[ELF] OUTPUT_FORMAT: support "binary" and ignore extra OUTPUT_FORMAT commands
This patch improves GNU ld compatibility.
Close #87891: Support `OUTPUT_FORMAT(binary)`, which is like
--oformat=binary
[ELF] OUTPUT_FORMAT: support "binary" and ignore extra OUTPUT_FORMAT commands
This patch improves GNU ld compatibility.
Close #87891: Support `OUTPUT_FORMAT(binary)`, which is like
--oformat=binary. --oformat=binary takes precedence over an ELF
`OUTPUT_FORMAT`.
In addition, if more than one OUTPUT_FORMAT command is specified, only
check the first one.

[ELF] Support --oformat= beside Separate --oformat
Both GNU ld's manpage and ours use --oformat= as the canonical form.
It's odd that we do not support it...

[ELF] --oformat=binary: use LMA to compute file offsets
--oformat=binary is rare (used in a few places in FreeBSD, see `stand/i386/mbr/Makefile` `LDFLAGS_BIN`)
The result should be identical to a normal output transformed by `objcopy -O binary`.
The current implementation ignores addresses and lays out sections by
respecting output section alignments. It can fail when an output section
address is specified, e.g. `.rodata ALIGN(16) :` (PR33651).
Fix PR33651 by respecting LMA. The code is similar to
`tools/llvm-objcop/ELF/Object.cpp` BinaryWriter::finalize after D71035 and D79229.
Unforunately for an output section without PT_LOAD, we assume its LMA is equal
to its VMA. So the result is still incorrect when an output section LMA
(`AT(...)`) is specified
Also drop `alignTo(off, config->wordsize)`. GNU ld does not round up the file size.

Avoid duplicated code.
This also fixes the linker script accounting for the ELF header in
some places but not in others.

Use od instead of hexdump.
od is defined by POSIX and exists since version 1 AT&T Unix.
hexdump is not part of any standard as far as I know.
So od is a better choice than hexdump.
