  4. Update to 15.0.3 

    This commit includes a patch to the QEMU test suite.
The tcg/multiarch/linux/linux-test.c file fails to
compile under -Wall with LLVM 15.0.3

This is likely due to [recent improvements][1] to the
-Wno-unused-but-set-variable diagnostic to fix false
negatives when post/pre increment/decrement operator
are involved.

The patch simply deletes the unused variable since
the semantics of the test will remain the same.

  1. Use python3.8 with QEMU configure 

    QEMU no longer supports python3.6, giving the following error when we
run build-toolchain.sh:

ERROR: Cannot use '/usr/bin/python3.6', Python >= 3.7 is required.
       Use --python=/path/to/python to specify a supported Python.

So let's update to python3.8.

  1. Change to use cmake cache files 

    cmake cache files are a popular idiom with cmake projects in general
and llvm-project specifically.  If we have luck using these in
the toolchain_for_hexagon repo, perhaps we could contribute them
to llvm-project to make it easier for others to reproduce this build
and easier for other llvm developers to see how our toolchain is built.

  3. Revert "Update QEMU to 8.1.0" 

    8.1.0 includes c42e77a90d9244c8caf76fe0e54f84200430a4e1 which removed
a fallback for MAP_FIXED_NOREPLACE, this causes the QEMU build to fail.
We will need to explore updating to a newer glibc or some kind of
workaround.

This reverts commit 5a08e99.

  2. Update to Ubuntu 20.04 

    We have been living on borrowed time -- QEMU has for some time
required Ubuntu 20.04 to build and recently has made changes that prevent
QEMU from building on the glibc from Ubuntu 18.04.   The ubuntu-based
toolchain built by this repo will depend on 20.04.

Update to 20.04 and make corresponding changes to the docker config
to support differences between 18.04 and 20.04.

  1. Limit the depth of the git log used for manifest 

    `git log` could end up generating an unnecessarily long manifest output.
It was chosen to avoid some pitfalls with unnecessarily long `git show`
output with the CPython repo.  This seems like a reasonable solution.
