Python3 need to be rebuilt after final system clang is built

[dslm4515]

When compiling Cython, Build fails:

error: command 'x86_64-pc-linux-musl-clang' failed: No such file or directory

Perhaps Python3 should either be rebuilt after final system clang OR compiled for llvmtools.

And if building graphene:

Build succeeds if a link is made:

Also intltool wasnt built for final system

python3 built for stage1 toolchain, via commit 9bca49d79657eead622d9ced2066ce1e721e7b43

[dslm4515]

For LLVM-15.0.6 build [on i686], python3 [for final system] build locks up under chroot. Last build command seen:

clang -shared build/temp.linux-i686-3.11/sources/Python-3.11.3/Modules/_ctypes/_ctypes.o build/temp.linux-i686-3.11/sources/Python-3.11.3/Modules/_ctypes/callbacks.o build/temp.linux-i686-3.11/sources/Python-3.11.3/Modules/_ctypes/callproc.o build/temp.linux-i686-3.11/sources/Python-3.11.3/Modules/_ctypes/cfield.o build/temp.linux-i686-3.11/sources/Python-3.11.3/Modules/_ctypes/stgdict.o -L. -L/usr/local/lib -lffi -ldl -o build/lib.linux-i686-3.11/_ctypes.cpython-311-i386-linux-musl.so

I'm not sure if its an issue with the hardware OR with my build instructions. I check if my amd64 build has the same issue

[dslm4515]

Fixed. Python3 now built after final system LLVM

Lockup of python3 on i686/i586 is still pending investigation.

Fixed. Python3 now built after final system LLVM

What was the problem then? I mean, that made the build hang.

[dslm4515]

The original problem (cannot use python3 from llvmtools as final system python3... was hoping to build python3 once for both llvmtools and final system) was resolved by building python once more.

I'll open another issue for the 32bit X86 build
