I'm getting these errors in config.log when I try to build:

gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

configure:4391: result: no

liblto_plugin.so is on my system in the PATH, so I'm kinda stumped. Also not sure what's going on with the 'unrecognized command line option' errors.

Earlier, it couldn't find the `cc1` binary, but I fixed that with a symlink. Not sure where I could add a symlink for this file, though.

Any thoughts? I was able to build OpenWRT without a hitch, so I think the issue is in something SudoWRT is doing.
