I'm also seeing this in a bootstrapped PGO build.

$ ./tools/clang/scripts/build.py --llvm-force-head-revision --without-android --without-fuchsia --pgo --bootstrap
https://source.chromium.org/chromium/chromium/src/+/master:tools/clang/scripts/build.py?q=f:tools%2Fclang%2Fscripts%2Fbuild.py&ss=chromium

It appears using LLD after profile generation in the final optimized Clang build. e.g.

  [72/3520] Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/ELFAttributeParser.cpp.o
  <unknown>:0: error: SHT_NOBITS section '__llvm_prf_cnts' cannot have non-zero initializers
