The variable CFLAGS contains the arguments to be passed onto gcc
while compiling.  In Makefiles, this variable is typically written as
a Makefile variable, and while running configure, it is usually
specified via an environment variable named CFLAGS (like in this case).

Here the arguments are:

-O6: Optimization level 6 (currently equivalent to -O3).

-pipe: Makes gcc use pipes instead of temp files.  Uses more memory
 but is faster.

Lokesh.
