…or LTO As described in this issue: zephyrproject-rtos/sdk-ng#1038 `-flto=auto` fails on some (slower) Windows machines due to an issue with the Zephyr SDK's GCC toolchain for Windows. In order to allow users to work around this issue, introduce a new CONFIG_LTO_SINGLE_THREADED option that switches to `-flto=1`, which enforces a single thread when processing LTO.
