Description of problem:
I have a x86_64 fedora 16 install and want to have a working gcc -m32, including compilation and linkage. To do that I try to install gcc.i686 while already having gcc.x86_64 installed. I got a transaction error because of a single point of conflict:

%{_prefix}/libexec/getconf/default is shared by both packages.

1. Is there another way to get gcc -m32 -o test test.c functional? (test.c is int main() { return 0; })?

I've tried to install gcc.i686 because yum provides "*gcc_s.so" showed only gcc.i686, before that stubs-32.h led me to install glibc-devel.i686, which did succeed (I have glibc-devel.x86_64 installed as well).

Version-Release number of selected component (if applicable):
gcc-4.6.2-1.fc16.x86_64
gcc-4.6.2-1.fc16.i686

How reproducible:
100%

Steps to Reproduce:
1. start with a F16 x86_64 install.
2. yum install gcc -y
3. add fedora32.repo, same as /etc/yum.repos.d/fedora.repo, just using arch=i386 (and renaming the sections to avoid name conflict)
4. yum install gcc.i686 -y
  
Actual results:
(the output is larger on initial install, I installed all the gcc prerequisites that were not conflicting before)

x86_64 garlic:gcc alon (f16)$ sudo yum install gcc.i686 -y

Error Summary
-------------


Expected results:
successful installation. gcc -m32 working.

Additional info:

I'm currently building a new local gcc package based on the following patch, it is simplistic - it doesn't take care of packaging the /usr/libexec/getconf/default file, but maybe something along these lines could work?
