[ros-arm-bringup] 32207: We now also implement InterlockedExchange (Fixes rtl build). We now set -lgcc for all builds (to get built-in division helpers), and also -static (not to import libgcc.dll -- it seems -static isn't needed on x86, but it is on ARM). We hackfix kdcom to use the FeroUart base address -- this driver won't be used for a while, but we need to have it built. Now binaries are being created properly (previously kernel was 15MB and importing .DLL files...). FreeLDR output: FreeLoa
