Forgot to add: this likely happens because you pass CFLAGS on the make's
command line, such as "make ... CFLAGS=...".  This way, make(1) actually
has two CFLAGS variables: command-line and global.  CFLAGS+= adds to the
global CFLAGS variable but ${CFLAGS} expands a value of the command-line
CFLAGS variable (which has a higher precedence).  Go learn the different
types of make variables in the make(1) manpage.
