Closing out as a duplicate of ASTERISK-20128.

As noted on that issue, previously Asterisk would pick the wrong CPU architecture which - since it did it 'automatically' - could not be configured or undone. You can deselect {{BUILD_NATIVE}} in menuselect to get Asterisk to not pass {{-march=native}} and use {{CFLAGS}} to otherwise tune the build process. While this may not be ideal, no one has proposed a better patch to the build system to work around this.
