John bebf09a3b3 qt5: update to 5.13.0 
qt5: update ppc64(le) support + add big endian

This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

This is a base patch that adds support for ppc64le glibc. Big endian and musl
support is added in extra patches afterwards.
Ping q66 if you're updating qt5 and the patch does not apply anymore.
