BACKENDS: RISC OS Scumm 2.6.0 fails to start on RISC OS Pyromaniac

[gerph]

Hiya,

Testing ScummVM 2.6.0 using the stable release (non-VFP) exits silently but produces an error during startup in the stderr log, but I don't know what other useful information would help. This was using riscos-stable-dffcaa5a.zip.

The log output in stderr is:

`
WARNING: elfloader: Symbol "PLUGIN_getBuildDate" not found.!
WARNING: elfloader: Failed loading symbol 'PLUGIN_getBuildDate' from plugin '/<ScummVM$Dir>/plugins/detection.plg'!
WARNING: elfloader: plugin '/<ScummVM$Dir>/plugins/detection.plg' is missing symbols!
Audio write: Digital Renderer is already active.

"/data/src/common/stream.cpp", line 132: virtual bool Common::MemoryReadStream::seek(int64, int): Assertion failed: _pos <= _size

Fatal signal received: Aborted

Obviously without any symbols present this makes it very difficult to see what it was trying to do.

Buildbot builds should now include function names for ScummVM code. Code in external libraries don't have function names yet, but if those are necessary I can provide a custom build with function names included.
