pw_toolchain: Use LLVM compiler-rt builtins Enable linking against LLVM compiler-rt builtins. To effectively link against builtins repo, the following properties need to be set. `dir_pw_third_party_llvm_builtins` - Directory where the LLVM compiler-rt repo is checked out. `pw_third_party_llvm_builtins_TARGET_BUILTINS` - Architecture specific pw_source_set created from builtins source files. e.g. arm_builtins. If this property is not set, no architecture specific builtin functions will be included from the repo. `pw_third_party_llvm_builtins_ignore_list` - Optional list of files to be excluded from builtins repo. The ignore list can also contain the files to be ignored from architecture specific pw_source_set.

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
