In the failing command (iossim-log) the syslibroot flag is being specified to the linker and the link command still fails, so your patch shouldn’t fix the problem. You can see that listed in iossim-link.txt.
The other error is (if anything) more disturbing. You’re generating a malformed libLLVMSupport. Not sure how that’s happening.
It looks to me like there is something wrong with your host toolchain. I don’t really know what else to say, but your patch shouldn’t have any impact on this problem since that flag is already being specified in the failing commands you’ve shown.
