The Linux Platform currently will only say the Host architecture is supported. This patch retains that behavior for the Host Platform, but adds a list of architectures for the Remote Platform.
Might as well throw "mips" in there while you're at it.
Thanks for adding MIPS! LGTM
Hey, do we need to enumerate all of the architectures? I put up http://reviews.llvm.org/D9672 to get non x86 working again where it queries the remote PlatformGdbServer if not the host. WDTY?
