Makefile.rules: use CFLAGS instead of CPPFLAGS
CPPFLAGS are flags for the preprocessor, not the C compiler.
clang warns when linking that we don't have the blx instruction:
lld.real: warning: lld uses blx instruction, no object with architecture
supporting feature detected
but this is because the linker command was not being passed the correct
architecture because it was missing the CFLAGS that specified them:
Before:
"/usr/bin/clang-8" -cc1as -triple armv4t-none-unknown-eabi
After:
"/usr/bin/clang-8" -cc1as -triple thumbv7em-none-unknown-eabi
