Package: llvm-toolchain-18
Version: 1:18.1.8-11
Trying to build llvm-toolchain-18 with profile `stage1` fails in the
following way:
# disable libc++-X.Y-dev-wasm32.install.in on old distro
if test "yes" = "no"; then \
echo "" > debian/libc++-18-dev-wasm32.install; \
echo "" > debian/libc++abi-18-dev-wasm32.install; \
else \
if ! dpkg -l|grep -q wasi-libc; then \
echo "Could not find wasi-libc on the system"; \
echo "Please check that the package is available on the system"; \
echo "it might be that the 'hello' package is installed by another
constraint"; \
exit 1; \
fi; \
fi
Could not find wasi-libc on the system
Please check that the package is available on the system
it might be that the 'hello' package is installed by another constraint

I think the correct way to solve this is to mark `hello` with `<!stage1>`
now that `spirv-tools` are marked as such in [1]. It does help to install
wasi-libc for the first stage.
The patch could look like this:
