[quake3] quake3 on Solaris x86

[vincent at cojot.name]

Here's a diff (backported from ioq2 code base) that fixes LoadTGA on 
Solaris/Sparc. I bet it applies to other arches too..
I'm going to audit the tr_image* code to check for other fixes..

Best regards,

PS: Now the client dies in as follows:
