More compatibility it's possible?

I'm not completely sure what you're asking for, but let me try.

You mean write a GCC back end so that GCC can generate WebAssembly (wasm)
code?  Yes, that can be done, but has not yet been done, and requires
quite a bit of effort.

It's on my (long...) list of interesting things to look into.  ;-)

I'm aware of Pip Cet's effort from two, three years ago: "Partial
WebAssembly backend",
<https://sourceware.org/ml/binutils/2017-03/msg00044.html>,
<https://sourceware.org/ml/binutils/2017-03/msg00073.html>.  See also the
referenced GitHub repositories ("asmjs" branches):
<https://github.com/pipcet/binutils-gdb/tree/asmjs>,
<https://github.com/pipcet/gcc/tree/asmjs>,
<https://github.com/pipcet/glibc/tree/asmjs>,
<https://github.com/pipcet/asmjs>, and "Dynamic Linking" blos posts on
<https://pipcet.github.io/>.

Some code got committed to binutils, but not (yet?) to GCC, and I don't
know what the overall status is.

Once GCC supports '--target=[WebAssembly]', it can then be ported so that
it can itself be compiled for/on a WebAssembly system (GCC native build),
and then run inside a WebAssembly "machine" (web browser).

You lost me here.  Is this about Microsoft's ".NET Standard"?

Are you asking for a GCC front end for WebAssembly (can be done, a lot of
effort), another GCC back end for ".NET Standard" (if that makes sense;
probably can be done, a lot of effort).
