isl: download failed

[randomizedcoder]

G'day,

I'm really trying to use https://github.com/trailofbits/ebpfault, which says it needs osquery-toolchain.

I've successfully built crosstool-ng ( https://github.com/crosstool-ng/crosstool-ng ), but ebpfault seems to want osquery-toolchain.

However, when trying to build osquery-toolchain it's failing to download "isl".

@alessandrogario @Smjert Either of you have guidance here?

Keep in mind that the repo here was updated to Clang 11 but osquery (and I think ebpfault too) still uses Clang 9, so ebpfault may have some issues compiling. This repo has also pre-built binaries, which I think were the ones that the ebpfault README was suggesting to use.
