Compilation not working for QNX

[pablorcum]

What version of protobuf and what language are you using?
Version: master
Language: C++

What operating system (Linux, Windows, ...) and version?
Host: Windows 10
Cross-compiling for QNX v7.1

What runtime / compiler are you using (e.g., python version or gcc version)
QNX SDP 7.1 - QCC v8.3

What did you do?
Steps to reproduce the behavior:

1. Build CMake project for QNX

What did you expect to see
Compilation working. It stopped working after #8106 that removed sys/param.h.

What did you see instead?
Source code does not compile due to missing endian.h.

Anything else we should know about your project / environment
It works by replacing
#include <endian.h> // __BYTE_ORDER
with
#include <sys/platform.h> // __BYTE_ORDER
Actually, sys/param.h is not required and sys/platform.h is enough to enable compilation in files src\google\protobuf\stubs\port.h and src\google\protobuf\io\coded_stream.h.

Could you add

#elif defined(__QNX__)
#include <sys/platform.h> // __BYTE_ORDER

in files changed in https://github.com/protocolbuffers/protobuf/pull/8106/files
