Yes, you do.  But I'm sure that you will find the make.conf(5) manpage
very informative and useful.  Especially the following parts:

|     The following list provides a name and short description for variables
|     that are used for all builds, or are used by the makefiles for things
|     other than builds. [...]
|
|     CFLAGS        (str) Controls the compiler setting when compiling C code.
|                   Optimization levels above -O (-O2, ...) are not supported.

I hope this helps a bit.
