It's very repetitive, so to give a flavour for it, here's i386, m68knommu
and fs/Kconfig.binfmt. I rewrote the BINFMT_AOUT helptext to bring it
into this decade.
Comments welcomed; I'll send it to Linus tomorrow if I don't hear anything.

-config BINFMT_AOUT
- tristate "Kernel support for a.out binaries"
- ---help---
- A.out (Assembler.OUTput) is a set of formats for libraries and
- executables used in the earliest versions of UNIX. Linux used the
- a.out formats QMAGIC and ZMAGIC until they were replaced with the
- ELF format.
-
- As more and more programs are converted to ELF, the use for a.out
- will gradually diminish. If you disable this option it will reduce
- your kernel by one page. This is not much and by itself does not
- warrant removing support. However its removal is a good idea if you
- wish to ensure that absolutely none of your programs will use this
- older executable format. If you don't know what to answer at this
- point then answer Y. If someone told you "You need a kernel with
- QMAGIC support" then you'll have to say Y here. You may answer M to
- compile a.out support as a module and later load the module when you
- want to use a program or library in a.out format. The module will be
- called binfmt_aout. Saying M or N here is dangerous though,
- because some crucial programs on your system might still be in A.OUT
- format.

-config BINFMT_ELF
- tristate "Kernel support for ELF binaries"
- ---help---
- ELF (Executable and Linkable Format) is a format for libraries and
- executables used across different architectures and operating
- systems. Saying Y here will enable your kernel to run ELF binaries
- and enlarge it by about 13 KB. ELF support under Linux has now all
- but replaced the traditional Linux a.out formats (QMAGIC and ZMAGIC)
- because it is portable (this does *not* mean that you will be able
- to run executables from different architectures or operating systems
- however) and makes building run-time libraries very easy. Many new
- executables are distributed solely in ELF format. You definitely
- want to say Y here.
-
- Information about ELF is contained in the ELF HOWTO available from
- <http://www.tldp.org/docs.html#howto>.
-
- If you find that after upgrading from Linux kernel 1.2 and saying Y
- here, you still can't run any ELF binaries (they just crash), then
- you'll have to install the newest ELF runtime libraries, including
- ld.so (check the file <file:Documentation/Changes> for location and
- latest version).
-
- If you want to compile this as a module ( = code which can be
- inserted in and removed from the running kernel whenever you want),
- say M here and read <file:Documentation/modules.txt>. The module
- will be called binfmt_elf. Saying M or N here is dangerous because
- some crucial programs on your system might be in ELF format.
-
-config BINFMT_MISC
- tristate "Kernel support for MISC binaries"
- ---help---
- If you say Y here, it will be possible to plug wrapper-driven binary
- formats into the kernel. You will like this especially when you use
- programs that need an interpreter to run like Java, Python or
- Emacs-Lisp. It's also useful if you often run DOS executables under
- the Linux DOS emulator DOSEMU (read the DOSEMU-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>). Once you have
- registered such a binary class with the kernel, you can start one of
- those programs simply by typing in its name at a shell prompt; Linux
- will automatically feed it to the correct interpreter.
-
- You can do other nice things, too. Read the file
- <file:Documentation/binfmt_misc.txt> to learn how to use this
- feature, and <file:Documentation/java.txt> for information about how
- to include Java support.
-
- You must say Y to "/proc file system support" (CONFIG_PROC_FS) to
- use this part of the kernel.
-
- You may say M here for module support and later load the module when
- you have use for it; the module is called binfmt_misc. If you
- don't know what to answer at this point, say Y.
