drop the async option from the wasm options. If a kernel really wants to be async, the flag can be set in the kernel directly.
force all kernels to use dynamic linking (even though atm this is only used by python, most kernels should use that, in particular lua and any upcoming R kernel)
In this PR we:
drop the async option function
added the needed flags for dynamic linking (MAIN_MODULE)
removed the filesystem option and just force a filesystem for all kernels
add POSITION_INDEPENDENT_CODE flag for all kernels, ie -fPIC, since this is mandatory for all used libraries when using dynamic linking.
remove superfluous flag XEUS_EMSCRIPTEN_WASM_BUILD to indicate emscripten build, we can just use EMSCRIPTEN which already does the job.
See https://github.com/jupyter-xeus/xeus-lite/issues/7 for details, but in a nutshell, we want all xeus-wasm kernels to be as similar / unified as we can. Therefore we:
