Unable to compile MIPS Go using steps provided in README

[jberlet]

Hello,
I am trying to compile the MIPS Go binary using the steps you listed and am getting the following error:
`./make.bash

Building Go bootstrap tool.

I tried setting the GOMIPS to GOMIPS=soft-float but then that generates the following error:
##### Building Go bootstrap tool. cmd/dist go: invalid GOMIPS: must be hardfloat, softfloat

It appears that my golang dev. environment is confusing the mips32 go environment I am trying to build for but I am not sure how to tell the main.bash bootstrap to ignore that environment setup.

Golang installed on my Rocky Linux desktop:
go1.18.3
Host OS (Linux): Rocky Linux release 8.5 (Green Obsidian)
All steps below (from your README) work except:
git clone https://go.googlesource.com/go go-mips32 cd go-mips32 git reset --hard 26e726c3092264584053a4f81714dcc8c91d2153 git pull https://go.googlesource.com/go refs/changes/58/37958/1 cd src GOROOT_BOOTSTRAP=/usr/local/go ./make.bash
**** Last line above Generates error mentioned earlier ****
Thank you!
