Toolchain with arm-meego-linux-gnueabi-gcc doesn't match Qt built with it

When I added the toolchain contained with compiler arm-meego-linux-gnueabi-gcc, Qt Creator detected it as:
arm-linux-meego-elf-32bit

However, when I added a Qt version built with that compiler, Qt Creator insists that there's no toolchain that can build it.

Inspecting the code, it turns out that the QtCore binrary is detected as "arm-linux-generic-elf-32bit". After all, there's no encoding in the ELF header for the MeeGo, Harmattan or Maemo flavours. But that means the ABI comparison (ProjectExplorer::Abi::isCompatibleWith) fails.

The code in isCompatibleWith accepts has a comment saying "// linux-generic is compatible with linux", however the comparison is inverted. The toolchain isn't generic.
