Error to find build id on OpenBSD

[lcheylus]

I'm trying to build and port tinygo on OpenBSD (current version on amd64).

• Build for LLVM from sources and tinygo OK

$ gmake llvm-source
(...)

$ export CC=clang
$ export CXX=clang++
$ gmake
(...)
$ ./build/tinygo version
tinygo version 0.32.0-dev-90b0bf64 openbsd/amd64 (using go version go1.22.2 and LLVM version 17.0.1)

When I try to build/run a Go binary from sources (here with a simple hello_world code), I have an error to find build id:

$ ./build/tinygo build -o ~/tmp/hello ~/tmp/hello_world.go
error: could not find build id in /home/<user>/dev/tinygo.git/./build/tinygo

After some debug, the case for OpenBSD is not handled in builder/buildid.go, function ReadBuildID.
