At the same time, this forces the flags used when compiling nspr (which, until we'd land a 4.9.1 beta, builds as armv5) independently of what nspr does by default, and adds the thumb default for iOS to the main configure.in (it was only added to js/src/configure.in). This also moves configure.in and js/src/configure.in parts in a semi-common (as in, forced to be synchronized) file.

We should probably just fix the mozconfigs at this point, since they're in-tree. (If this comment even still applies.)

Can we get a comment here with a brief summary of what this does? Even just "configure platform-specific CPU architecture compiler options" or something like that.

I'll just remove that when landing: the only mozconfigs that were using this are the android-nothumb ones, and they are gone.

Backed out, because it turns Windows red:

This solves the windows problem.
