fetching submodules requires authentication for qemu

[chamalis]

Reproduce:

git clone https://github.com/riscv-collab/riscv-gnu-toolchain rgt
cd rgt
git submodule update --init --recursive

Output:

Submodule 'binutils' (https://sourceware.org/git/binutils-gdb.git) registered for path 'binutils'

I have opened all the repos in .gitmodules file, at the browser, they open without any auth, only one typo (fixed in latest PR).

Probably the same issue as raised here in this closed issue?

• “git submodule update --init --recursive” failed #480 (comment)

Unfortunately my attempt to address it got stuck:

• “git submodule update --init --recursive” failed #480 (comment)

[TommyMurphyTM1234]

The workaround for the moment is to let the top level riscv-gnu-toolchain Makefile update/clone the submodules rather than manually doing a recursive update which is actually not necessary in order to build the riscv-gnu-toolchain tools.

Thanks Tommy.
Indeed, the github search in issue pages didn't find that issue.
The problem is when letting makefile handle it, this doesn't build all the extensions:

./configure --prefix=/opt/riscv --enable-multilib

I don't understand.

1. What exactly do you mean by "build all the extensions"?
2. What has this got to do with the QEMU recursive clone issue?

No, this is just a duplicate of #1613 - the subhook module was missing, so the qemu respository needs to be updated if you want recursive cloning to work.

Link to posts that explain how to bump QEMU which I will do when 9.2 releases imminently:
