so, there isn't problem, but CFLAGS="" emerge wxGTK produces:

and -O2 is added. Simple sed fix this issue and works for me: sed -i 's/-O2//g' configure

If you don't set CFLAGS then the package is free to set them itself.  It's only a bug if it overwrites them.

is not invalid for me. Why if i set cflags to ="" it should be compiled with -O2 ?

Packages need to respect user CFLAGS, but if you don't give any then it should use sane defaults.  A lot of software won't build with -O0.
