mingw expected in incorrect location (tinygo-macos)

Error about _mingw.h.in

GOOS=windows GOARCH=amd64 tinygo build .

error: open ~/.local/opt/tinygo-0.30.0/lib/mingw-w64/mingw-w64-headers/crt/_mingw.h.in: no such file or directory

Actual Location

The actual location appears to be...

pushd ~/.local/opt/tinygo/
fd | rg 'mingw'

~/.local/opt/tinygo/lib/mingw-w64/mingw-w64-headers/_mingw.h.in

[coolaj86]

Workaround

Go to the mingw-w64-headers and link itself to crt:

pushd ~/.local/opt/tinygo-0.30.0/lib/mingw-w64/mingw-w64-headers/
ln -s ./. ./crt

Though... that lead me to the next error:
