Rustdoc fails to build wasm32 target documentation

[o01eg]

When I build rust from master branch I catch error on documenting std for wasm32 target:

[o01eg]

What about to use #43348 to make other platforms available when building rust from sources?

[jyn514]

Same issue as in #74976 (comment). Relevant code:

rust/library/std/src/sys/mod.rs

Lines 66 to 72 in 5b04bbf

	} else if #[cfg(any(target_os = "cloudabi",
	target_os = "hermit",
	target_arch = "wasm32",
	all(target_vendor = "fortanix", target_env = "sgx")))] {
	// On CloudABI and wasm right now the module below doesn't compile
	// (missing things in `libc` which is empty) so just omit everything
	// with an empty module

Maybe it's as simple as removing that else if #[cfg]?

Maybe it's as simple as removing that else if #[cfg]?

It is not.
