Add support for OpenBSD

[Anthony J. Bentley]

Make these libraries compile on OpenBSD and fix all remaining issues.

FCollada r11936
nvtt ​upstream bug report
SpiderMonkey (probably needs --disable-tracejit)

Full build log

I should probably add that this is on amd64.

You probably need to search for __FreeBSD__ in all the FCollada source files and add a check for __OpenBSD__ as well. I don't know if that will fix this particular error but it's likely required for a successful build.

[Anthony J. Bentley]

You're right, it doesn't fix this particular error, but I'll attach the patch anyway. Initial problem is still present.

[Anthony J. Bentley]

Patch that adds OpenBSD to #ifdefs.

[historic_bruno]

In FCollada/FUtils/FUStringBuilder.h, change line 138 to:

#elif defined(__APPLE__) || defined(__OpenBSD__)

which makes sense if it works, since OS X builds on BSD in many respects (not sure why this fix isn't required on FreeBSD as well...)

[Anthony J. Bentley]

That fix (combined with the patch I attached above) allows FCollada to build on OpenBSD. Thanks.

[historic_bruno]

Good to hear :) How does the rest of the build go? If that's all we need, I'll commit the fixes.

[Anthony J. Bentley]

Spidermonkey won't configure unless I pass --disable-tracejit to it. When that's done, the build fails here:

I currently tell 0ad to use the system spidermonkey (1.9.2.16). No doubt this will cause errors later on down the line.

nvtt doesn't build either. I opened a bug upstream: ​https://code.google.com/p/nvidia-texture-tools/issues/detail?id=176

In 11936:

Make FCollada compile on OpenBSD, based on patch by anthonyjbentley. Refs #1463.

Thanks for the patch. I modified the ticket to add support for OpenBSD. I'll probably give the remaining issues a try in the next days, but if you have some other patches just add them here.
