Since the script depends on several specific tools (clang, wasm-opt, wasmtime, and a specific SYSROOT), it might be a good idea to move all the path exports and environment variable setups to the top of the script using fallbacks like this:

export CLANG="${CLANG:-/home/lind/lind-wasm/clang+llvm-16.0.4-x86_64-linux-gnu-ubuntu-22.04/bin/clang}"
export CXX="${CXX:-/home/lind/lind-wasm/clang+llvm-16.0.4-x86_64-linux-gnu-ubuntu-22.04/bin/clang++}"
export AR="${AR:-/home/lind/lind-wasm/clang+llvm-16.0.4-x86_64-linux-gnu-ubuntu-22.04/bin/llvm-ar}"
export LD="${LD:-/home/lind/lind-wasm/clang+llvm-16.0.4-x86_64-linux-gnu-ubuntu-22.04/bin/wasm-ld}"
export RANLIB="${RANLIB:-/home/lind/lind-wasm/clang+llvm-16.0.4-x86_64-linux-gnu-ubuntu-22.04/bin/llvm-ranlib}"

export WASM_OPT="${WASM_OPT:-/home/lind/lind-wasm/tools/binaryen/bin/wasm-opt}"
export WASMTIME="${WASMTIME:-/home/lind/lind-wasm/src/wasmtime/target/debug/wasmtime}"

export SYSROOT="${SYSROOT:-/home/lind/lind-wasm/src/glibc/sysroot}"

export CFLAGS="${CFLAGS:---sysroot=$SYSROOT -g -O2}"
export CXXFLAGS="${CXXFLAGS:---sysroot=$SYSROOT -g -O2}"
export LDFLAGS="${LDFLAGS:---sysroot=$SYSROOT -Wl,--import-memory,--export-memory,--max-memory=67108864,--export=__stack_pointer,--export=__stack_low}"

This way you could modify them at the time you call the compile without having to edit the script, like this:
WASMTIME=$HOME/.cargo/bin/wasmtime ./compile_lmbench.sh

And if you later want to move it to the Makefile to adhere to the build contract style we talked about in Issue 10

@m-hemmings this is where the sysroot stuff comes into play, I like your overlay idea but i'm not sure runbin and I completely understand it

@rennergade The idea should be that the app does all it needs to in its own context and then the tooling script moves what needs to be moved. So I wonder, could this merge be done in the app's own folders and then have the merged file be placed in the sysroot_overlay folder with the same folder structure it would need if it went to sysroot? or is it required that it be done in situ in the actual sysroot?
The original idea was that the app would not modify the actual sysroot at all, but we can revisit that if it doesn't fit
