Description of problem:
Hello

I wanted to use the setarch command to make yum use i386 repositories instead of x86_64. This is needed when you want to resolve the issues with 32bit plugins and Firefox. My repositories are configured to use $basearch variable, and from what I have found on google, this variable is taken from uname -m output. Since setarch affects this output yum should also use relevant repositories, but it sill uses x86_64 although setarch was set to i386.

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


How reproducible:
Always

Steps to Reproduce:
1. set all repositories to use $basearch var in place of architecture in .repo files
2. setarch i386 yum update
3. yum still uses x86_64..
  

Actual Results:  yum uses x86_64 instwad of what was set via setarch command

Expected Results:  yum should use architecure whatever was set by setarch

Additional info:

uname -m gives x86_64

setarch i386 uname -m gives i686 (not 386, but in this case yum should at least to fail to retrieve repomd.xml instead of using x86_64)
