This needs to be added to the .rpmrc file in the mock root (from what
I've gathered in other threads).  You should be able to use this sort
of thing in your mock config:

config_opts['files']['path/name/no/leading/slash'] = "file contents"

I think you'll want something about like this (untested ;)):

config_opts['files']['builddir/.rpmrc'] = """
optflags: i386 -O2 -g -m32 -march=i386 -mtune=generic -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: i486 -O2 -g -m32 -march=i486 -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: i586 -O2 -g -m32 -march=i586 -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: i686 -O2 -g -m32 -march=i686 -mtune=generic -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: pentium3 -O2 -g -m32 -march=pentium3 -mtune=generic -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: pentium4 -O2 -g -m32 -march=pentium4 -mtune=generic -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: athlon -O2 -g -m32 -march=athlon -fasynchronous-unwind-tables -Werror-implicit-function-declaration
optflags: ia64 -O2 -g -m64 -mtune=generic -Werror-implicit-function-declaration
optflags: x86_64 -O2 -g -m64 -mtune=generic -Werror-implicit-function-declaration
optflags: amd64 -O2 -g -mtune=generic -Werror-implicit-function-declaration
optflags: ia32e -O2 -g -m64 -mtune=generic -Werror-implicit-function-declaration
...
"""

You'll want to grab the optflags settings from a rawhide box.  The
snippet above is from F8 (though I don't know that any of the values
changed in rawhide).
