build.log
The error suggests recompiling with -fPIC but the build log suggests this is unsupported:
-- Linker detection: GNU ld
-- Performing Test C_SUPPORTS_FPIC
-- Performing Test C_SUPPORTS_FPIC - Failed
-- Performing Test CXX_SUPPORTS_FPIC
-- Performing Test CXX_SUPPORTS_FPIC - Failed
CMake Warning at /usr/lib/llvm/14/lib/cmake/llvm/HandleLLVMOptions.cmake:276 (message):
-fPIC is not supported.
FWIW, same version built fine half a year ago:
2022-08-09T18:32:40 >>> sys-devel/clang-14.0.6-r1: 26 minutes, 38 seconds
At that time, it was built using sys-devel/gcc-11.3.0. I've tried with gcc:11 (11.3.1_p20230120-r1), but this causes other problems:

collect2: error: ld returned 1 exit status
Adding this to /etc/portage/env/sys-devel/clang does fix it:
CFLAGS="${CFLAGS} -fPIC"
CXXFLAGS="${CFLAGS} -fPIC"
The question is: why is this needed all of a sudden?
