Bugzilla Bug 89990

Prboom 2.2.4 builds and runs fine on my Sun Blade 100, when forcing
ACCEPT_KEYWORDS=x86, but does not have sparc or ~sparc keywords.
I haven't tested openGL, as I have no 3d hardware in my machine but with
USE=-opengl the game runs fine.

Reproducible: Always
Steps to Reproduce:
1. # emerge prboom

Actual Results:  

Calculating dependencies
!!! All ebuilds that could satisfy "prboom" have been masked.
!!! One of the following masked packages is required to complete your request:
- games-fps/prboom-2.2.4-r1 (masked by: missing keyword)

For more information, see MASKED PACKAGES section in the emerge man page or
section 2.2 "Software Availability" in the Gentoo Handbook.

Expected Results:  
Built and installed correctly, as with ACCEPT_KEYWORDS=x86 emerge prboom

I hope this is the right place for this, please email me if it isn't, and I'll
post correctly next time.

Keyworded ~sparc.
Thanks for the report!
