Error compiling Mono compiler by following instructions

[ChristianWeyer]

Hi there!

This looks very promising :-)

I am on macOS with (hopefully) all tools installed. When following the instructions I get an error for 'Now, we can now build the Mono compiler itself':

$ cd ~/src/mono-wasm
$ git clone git@github.com:lrz/mono-wasm-mono.git mono-compiler
$ cd mono-compiler
$ ./autogen.sh --host=i386-darwin --with-cross-offsets=offsets-wasm32.h CFLAGS="-DCOMPILE_WASM32 -DMONO_CROSS_COMPILE" CXXFLAGS="-DCOMPILE_WASM32 -DMONO_CROSS_COMPILE" --disable-boehm --with-sigaltstack=no --enable-llvm --enable-llvm-runtime --with-llvm=../llvm-mono-build --disable-btls --with-runtime_preset=testing_aot_full
$ cd eglib
$ make
$ cd ../mono
$ make

The last make produces this error:

  mono git:(master) make

Is there anything I am missing? Thanks!

Any ideas @lrz ? Thanks!
