[bug#64211] [PATCH] gnu: Add wasi-libc.

[Felix Lechner via Guix-patches via <guix-patches@gnu.org>]

* gnu/packages/wasi.scm: New file.
* gnu/packages/wasi.scm (wasi-libc): New variable.

The lint run shows this message but as far as I can tell it's bogus:

gnu/packages/wasi.scm:31:12: warning: no valid tags found for wasi-libc
