# Deliberately not cmake/cortex_m3.cmake or cmake/cortex_m4.cmake.  Those add
# -mlong-calls to every C file, and under -fpic that routes every call in a
# module through its GOT, including the shell entry's call to the function that
# fills the GOT in; and they leave the floating-point unit off, which the
# Cortex-M4 module port needs on to exercise its lazy-stacking paths.  The CPU
# and FPU flags are chosen per port in CMakeLists.txt instead.
