Compiling to WASM fails

[barracuda156]

Describe the bug
Compilation to WASM fails.

To Reproduce
Steps to reproduce the behavior:

1. Edit build target:

build:
	GOOS=wasip1 GOARCH=wasm go build -ldflags="-s -w" -gcflags='all=-N -l'

2. Run make build, see the error.

Expected behavior
Hopefully it can work.

Many of lazygit's dependencies don't support wasm, as you can see from the build log. It's not lazygit's code itself that is the problem here.

But I'm curious: why do you want to build for wasm? What's your goal?

For platforms where Go itself is broken (a lot of macOS versions, Linux and *BSD on ppc, etc.) it seems to be possible, at least in principle, to compile to wasm and then to C. On a toy example it works. With real apps, as we can see, there are issues.
