glm: fix gcc 7.3 support

[sifmelcara]

Motivation for this change

slop fails to build after switching to gcc 7.3

The reason seems to be that glm did not correctly support gcc 7.3 . Although this issue have been fixed by upstream in g-truc/glm@dd48b56 , they haven't release any stable version contains the fix.
This PR fixes the issue by fetching new version of platform.h. (patches and fetchpatch cannot be used because that commit have some content which cannot be automatically merged)

BTW, tag 0.9.9-a2 is not a release? (only alpha, I suppose)

[sifmelcara]

Yeah, I guess it means alpha.

[sifmelcara]

Hmm, both of my machines failed nox-review

make[1]: *** [/tmp/nix-build-libreoffice-5.3.6.1.drv-0/libreoffice-5.3.6.1/postprocess/CustomTarget_images.mk:37: /tmp/nix-build-libreoffice-5.3.6.1.drv-0/libreoffice-5.3.6.1/workdir/CustomTarget/postprocess/images/images_breeze_dark.zip] Error 5

Not sure what is the cause of the failure.

Too small /tmp?

[sifmelcara]

I don't think so.. I have tried to remount /tmp to 10GB, still have out of space error

[Fuuzetsu]

It might not be using /tmp, for example on NixOS. Set TMPDIR. I would prefer a tagged version. I don't really know anything about this package, I was merely listed as maintainer so I could receive updates when new versions came out upstream from a monitoring tool we had so I can't offer much insight into any specifics.

[sifmelcara]

After I run nox-review on a linux machine with more than 60GB /tmp, it passed. It turns out even 10GB space may not be enough to build libreoffice.
Ok, so I will try to go for 0.9.9a2, and test if things like libreoffice and slop still work.

[sifmelcara]

I ended up adding another version of glm, and use that new version of glm to build slop.

[sifmelcara]

Sorry for the mess, in fact we still need to patch 0.9.5.

We should patch the glm-0.9.5, not update to glm-0.9.9-a2 because:

• openrw, kicad-unstable, gource, and logstalgia: they depend on glm, currently fails to build on master, works if we patch 0.9.5, fails if we update glm to 0.9.9-a2
• slop and maim: depend on glm, currently fails to build on master, works if we patch 0.9.5 or update to 0.9.9-a2
• libreoffice, odpdown, arx-libertatis and libreoffice: depend on glm, always success to build

So the only way to make all packages depends on glm builds with gcc 7.3, is to patch glm 0.9.5

[sifmelcara]

I think this is ready to be merged.
(To sum up, this PR will fix the build of openrw, kicad-unstable, gource, logstalgia, slop and maim.)
