Why do you think this is needed?
-m32 already appears in ldflags under target_arch==ia32.
It's wrong to add it for any other target_arch.

[robertm, 2012/10/11 19:28:43]

The problem is that I need to force the host compiler to be 
ia32 because v8 requires.
I could not find a good way to do so.
So I just added -m32 to CC.host.
This this not take care of the linker however, hence this change.
If there is a better way to force ia32 that would be definitely preferable.

If it's for the host, then shouldn't it be inside a '_toolset=="host"'
conditional of some kind?  This looks to me like it's going to apply to
'ldflags' used with CC.target too.
