Woops i forgot to fix the revision

Let's drop this line, wrksrc="$pkgname-$version" is the default, so we don't have to overwrite it.

[abenson]

I agree, this is vestigial from when the package was named libGL

[HadetTheUndying]

I'll get to this in the morning but just to clarify you are recommending removing the wrksrc line entirely? Since the default behavior makes it unnecessary?

[paper42]

Yes, we don't need to specify variables that are unnecessary.

[HadetTheUndying]

Okay it's spitting out new errors haha

[HadetTheUndying]

So i'm not sure why that failed to fetch the archive for the i686 build because it fetches fine on my systems.

Sorry I was out at the time. I intended to do this this morning. Looks like it already merged?
