David Anderson	0498d5ea86	tool/gocross: delete bootstrap tarball downloads after use ... Signed-off-by: David Anderson <danderson@tailscale.com>	2023-03-15 11:55:02 -07:00
David Anderson	df3996cae3	tool/gocross: bootstrap correctly on an older toolchain ... Sometimes, our cached toolchain ends up being an older version of Go, older than our go.mod allows. In that scenario, gocross-wrapper.sh would find a usable toolchain, but then fail to compile gocross. This change makes the wrapper script check that the cached toolchain's minor version is good enough to build tailscale.com, and re-bootstraps in shell if not.

David Anderson	64181e17c8	tool/gocross: support local toolchain for development ... This makes gocross and its bootstrap script understand an absolute path in go.toolchain.rev to mean "use the given toolchain directly".

David Anderson	7444dabb68	tool/gocross: do all the bootstrap steps in a subshell ... This avoids accidentally overwriting variables from the input environment, which might non-deterministically change the behavior of gocross.
