Providing 'hsdis' binaries not possible because of GPLv2/GPLv3 license clash

Hi Dalibor,

Firstly, apologies for the snark in my previous email.

I've also been looking into alternative decompilers and found this:

It's LGPL which in my understanding would be OK to distribute (not looking
for confirmation).

Possibly less useful than the binutils disassembler as it's x86 / x86_64
only (Making an assumption that binutils works with JIT-produced ARM,
sparc, MIPS, etc.)

Ultimately, if you care about the disassembly out of more than curiosity
then you've probably got the brains to build hsdis yourself.

I'll try and give both of the above a test and report back.
