Failed to build the Moddable Wasm tools

[stc1988]

Build environment: macOS
Moddable SDK version: 8.1.1
Target device: Wasm

Description
A brief summary of the problem

Steps to Reproduce

1. cd ${MODDABLE}/build/makefiles/wasm && make

make -f tools.mk
tools.mk:174: *** commands commence before first target.  Stop.
make: *** [debug] Error 2

This is caused by a missing backslash.

After making this fix, another issue occurred.

Thanks for the report. We've resolved these two issues. We've also made some small adjustments for compatibility with the latest emscripten. Those changes will land in our June release.
