Update document for MacOS compilation (#1770)

Browse Source 
When building LLVM, if multiple SDKs are installed in `/Library/Developer/CommandLineTools/SDKs`,
headers from multiple SDKs are picked, generating build errors as describe here:
    https://github.com/bytecodealliance/wasm-micro-runtime/issues/1758.

Without disabling the bound checks (i.e. -DWAMR_DISABLE_HW_BOUND_CHECK=1)
when building `iwasm`, the `-g=127.0.0.1:1234` parameter makes the runtime crash.

Update the document to avoid the issues.
