At last GCC-5.3.0 for N900! Actually everything what have been said for gcc-4.8 still applies: https://talk.maemo.org/showthread.php?t=90542

You can download it from my public google-drive:

Download size is 288MB and unpacked size even more.

Unpack to the /opt and tune your PATH.

It is configured with --disable-lto, I'm just testing could it be enabled and it is useful or not.
