test case

Description of problem:
The problem was originally encountered with sdlmame from RPM Fusion nonfree repository - the source RPMs are huge and thus I'll just link to CVS:

http://cvs.rpmfusion.org/viewvc/rpms/sdlmame/F-10/?root=nonfree

If you drop ARCHOPTS=-Upowerpc from the spec, the build will fail at the linking stage claiming that cpu_disassemble_powerpc is missing. I also found the attached test case in the web. Apparently, for some reason cpu_disassemble_powerpc will get relabeled as cpu_disassemble_1 - first hand info is available on http://forums.ps2dev.org/viewtopic.php?t=12314. As said before, adding -Upowerpc to cflags works this issue around. This affects ppc and ppc64 in  all released branches (F-10, F-11 and F-12; devel is probably affected as well but since ppc was dropped it does not really matter.

Version-Release number of selected component (if applicable):
4.3.2-7

How reproducible:
always

Steps to Reproduce:
1. gcc hello.c -S 
2. head hello.s
  
Actual results:
label cpu_disassemble_1 against cpu_disassemble_powerpc, powerpc name was replaced with 1

Expected results:
No replacement occurs.

Additional info:
I'm not really sure what I'm talking about, I'm just a packager. If you need any more data, I'll relay the information to the appropriate people.
