qt5base: Add support for MIPS64 BigEndian

This patch adds support for MIPS64 BigEndian platforms and has already
been merged upstream:

https://github.com/qtproject/qtbase/commit/cea101bd10cc158b97d5fbf45b33dad9b649c08b

Now we can remove the restriction on the Config.in to disable the
selection of this packages on MIPS64 BigEndian platforms.

+Subject: [PATCH] qtbase: Fix build error on 64bit BigEndian platforms
+
+The functions fromBytesToWord() and fromWordToBytes() are called when
+building on 64bit BigEndian platforms. It fails because those
+functions are disabled on the source code. Enabling those functions for
+64bit BigEndian platforms fixes the problem.
