The build environment might want to pass extra CFLAGS or LDFLAGS to the build of the acrn tools. With conventional build systems like automake, Meson, etc this is possible by just setting CFLAGS and LDFLAGS in the environment. However as the tools are built using bare Makefiles, these environment variables are overwritten. Respect them by renaming the variables in the Makefiles to e.g. LOG_CFLAGS and adding CFLAGS to that.
