Add --enable-first-stage-cross configure option
Build static-only, C-only compiler that is sufficient to cross compile
glibc. This option disables various runtime libraries that require
libc to compile, turns on --with-newlib, --without-headers,
--disable-decimal-float, --disable-shared, --disable-threads, and sets
--enable-languages=c.
Rationale: current way of building first stage compiler of a cross
toolchain requires specifying a list of target libraries that are not
going to be compiled due to their dependency on target libc. This
list is not documented in gccinstall.texi and sometimes changes. To
simplify the procedure, it is better to maintain that list in the GCC
itself.
Usage example as a patch to glibc's scripts/build-many-libcs.py:

Ping: [PATCH] Add --enable-first-stage-cross configure option

Add --enable-first-stage-cross configure option
Build static-only, C-only compiler that is sufficient to cross compile
glibc. This option disables various runtime libraries that require
libc to compile, turns on --with-newlib, --without-headers,
--disable-decimal-float, --disable-shared, --disable-threads, and sets
--enable-languages=c.
Rationale: current way of building first stage compiler of a cross
toolchain requires specifying a list of target libraries that are not
going to be compiled due to their dependency on target libc. This
list is not documented in gccinstall.texi and sometimes changes. To
simplify the procedure, it is better to maintain that list in the GCC
itself.

I think this is a great idea.
I don't think it makes any difference to this patch, but I've just
committed a change to libstdc++ so that you no longer neeed to add
--with-newlib when libstdc++ is configured with --without-headers
(because it's counter-intuitive to have to say which libc you're using
when not using any libc).
I only tested it for --disable-hosted-libstdcxx --without-headers
because I am not sure what libstdc++ even does if you build it hosted
but --without-headers.

I'm not really sure we need a patch for this. Isn't it sufficient to
"make all-gcc && make all-target-libgcc"? Folks have been doing that
for decades.

Oh, I did not know that "make install-gcc install-target-libgcc" works in this case.
So in the end, patch simplifies quirky first stage cross tool build procedure from
configure --target=$target --enable-languages=c --disable-threads --disable-shared # plus --with-newlib when --with-sysroot=
make all-gcc all-target-libgcc
make install-gcc install-target-libgcc
to
configure --target=$target --enable-first-stage-cross
make
make install
Either way is more or less okay for me, it just needs to be documented.
