[Buildroot] [git commit] package/asterisk: remove default -O3 optimization flag

commit: https://git.buildroot.net/buildroot/commit/?id=eaba3c8e131e21c4bae79483211685942e035300
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Actually asterisk package gets built with -O3 cflag since it's defaulted
into its sources, but it's not what we want, so let's empty its OPTIMIZE
Makefile variable letting Buildroot CFLAGS to take place instead.
