I was able to build with clang-11 from apt.llvm.org.

[ build-time ]

Normally, it takes me approx. 05:00 to build with clang-10
(10.0.1-rc1) and Linux v5.7-rc7.

This time start: 21:18 and stop: 03:45 means 06:27 - took 01:27 longer.

Samsung Ultrabook 2nd generation aka Intel Sandybridge CPU with 'make -j3'.
