electrs: Fails compiling against Bionic libc

Compiling against Bionic libc with the Android NDK gives:

   Compiling sysconf v0.3.4
error[E0081]: discriminant value `96` already exists

Looks like it’s an issue with the sysconf dep. Is it possible to work around this?

@ulzeraj could you try to apply this patch?

Thanks!

It seems to get worked until a point where it tries to use llvm-config. LLVM/Clang is the main compiler on this version of FreeBSD but apparently this tool wasn’t included. I’m installing the llvm version from ports and will report back once its finished compiling.

The tooling I’m using to create the Android build actually supports having a load of *.patch files it’ll automatically apply after pulling the source so I’ll have a go at patching this on my end for now.

Thanks!

Taking a look at it.
