Steps to reproduce

Install SmartOS
Login as root (over SSH)

Create zone (https://wiki.smartos.org/how-to-create-a-zone/):

imgadm import cfa9c88e-03f8-11eb-9980-879ff7980a9f # 20.3.0 64-bit
vmadm create <<EOL

{
    "brand": "joyent",
    "image_uuid": "cfa9c88e-03f8-11eb-9980-879ff7980a9f",
    "alias": "avalanchego",
    "hostname": "avalanchego",
    "resolvers": ["8.8.8.8", "8.8.4.4"],
    "max_physical_memory": 2048,
    "maintain_resolvers": true,
    "nics": [
       {
         "nic_tag": "admin",
         "ip": "dhcp"
     }
 ]
}
EOL

Login to zone: zlogin <uuid>
Install build dependencies: pkgin install go115 git gcc9 gcc9-libs

Set GOPATH:

export PATH=$PATH:$(go env GOPATH)/bin
export GOPATH=$(go env GOPATH)

Create a disk-based tmp directory, by default SmartOS zones use a RAM-disk tmpfs which has only 256 MB allocated (and we don't want to waste RAM on this):
```
mkdir -f tmp
export TMPDIR=~/tmp
```

Clone and build custom fork of coreth (https://github.com/ava-labs/coreth):

git clone --branch solaris_fixups https://github.com/dokterbob/coreth.git ~/go/src/github.com/ava-labs/coreth

Follow variant of official installation instructions (https://github.com/ava-labs/avalanchego):
```
go get -v -d github.com/ava-labs/avalanchego/...
cd $GOPATH/src/github.com/ava-labs/avalanchego
scripts/build_avalanche.sh
mkdir build/plugins
scripts/build_coreth.sh ~/go/src/github.com/ava-labs/coreth build/plugins/evm
```
The latter command seems to arbitrarily fail with /opt/local/go115/pkg/tool/solaris_amd64/link: running gcc failed: wait: no child processes and needs to be repeated until a working binary comes out. This is possibly due to an out of memory or similar condition.
Run avalanchego like a true boss:
```
./build/avalanchego
```
