Some more file/path restructuring.
All #includes now explicitly use the "<libopencm3/stm32/rcc.h>" format. If you want to get rid of the "libopencm3" prefix in your local project you can add a respective -I entry in your Makefile (not recommended though). All .ld files and .a libs are installed in $(TOOLCHAIN_DIR)/lib directly (as before), but are now renamed to avoid potential conflicts now or in the future. Examples: libopencm3_lpc13xx.a libopencm3_lpc13xx.ld libopencm3_stm32.a libopencm3_stm32.ld
