this is caused by a change in cmake see also https://gitlab.kitware.com/cmake/cmake/-/issues/21469 a temporary fix for now is to downgrade cmake to something <3.19.0 it seems the cmake change would be reverted in cmake-3.19.1. furthermore compiler-rt-sanitizers has adjusted its buildsystem to the cmake change but that needs a backport of the fix to the 11.0. branch
After temporary downgrade cmake to 3.18 it compiled as expected. Created the following bug to ask for cmake slotting: https://bugs.gentoo.org/756070
with cmake-3.19.1, which is in ::gentoo now, it compiles...
