CMake Build: Add QNX 7.1 build support
This commit allows building Qt6's QtBase using QNX 7.1 and a toolchain
file which is almost identical to what CMake has in its documentation:
https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-for-qnx
set(CMAKE_SYSTEM_NAME QNX)
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER q++)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
set(CMAKE_SYSROOT $ENV{QNX_TARGET})
The only difference is the usage of q++ instead of QCC, which is no
longer present in QNX 7.1 SDK.
Task-number: QTBUG-83202
Change-Id: I51031540721275f2ee83cee9e7df4994a65db0e2
