src/make.*: make --no-clean flag a no-op that prints a warning

2021-08-11T22:07:50+00:00

This flag is undocumented and is no longer useful. Users who want to
install additional toolchains without cleaning the installed packages
should just use `go install`.

This CL changes cmd/dist to print a warning that --no-clean is
deprecated and to advise users to use `go install std cmd` instead,
and then otherwise ignores it:

```
$ ./make.bash --no-clean
Building Go cmd/dist using $GOROOT_BOOTSTRAP. (devel +b7a85e0003 linux/amd64)
warning: --no-clean is deprecated and has no effect; use 'go install std cmd' instead
Building Go toolchain1 using $GOROOT_BOOTSTRAP.
```

Fixes #47204.

make.bash: fix misuse of continue

2021-05-18T15:00:55+00:00

Apparently, in bash, the "continue" keyword can only be used
inside of a loop, not in an if block. If readelf exists but $CC
does not, make.bash emits a warning:

./make.bash: line 135: continue: only meaningful in a `for', `while', or `until' loop

Change it to a conditional.

make.bash: this change modifies Go to correctly select a dyamic linker

2021-03-19T22:32:03+00:00

Alpine Linux is not the only musl-based Linux distribution. Checking for
/etc/alpine-release excludes many other distributions (Oasis, KISS,
Sabotage, sta.li). Not having the correct GO_LDSO set during go builds will
result in the wrong linker/loader on nonalpine musl systems for pie builds.
Instead, the dynamic loader should be checked for every system and set. This
results in the correct dynamic linker being found on glibc systems
(/lib/ld-linux-x86-64.so.2) and musl systems (/lib/ld-musl-x84_64.so.1).

Fixes #45034

make.bash: avoid warning when bootstrap doesn't support GOOS/GOARCH

2020-09-21T16:50:07+00:00

Currently, if make.bash is run with a GOOS or GOARCH that the
bootstrap toolchain doesn't support, it will print an ominous but
harmless warning like:

  2020/09/21 09:05:27 unsupported GOARCH arm64

This comes from the invocation of "go version" to get the exact
bootstrap toolchain version.

Since the GOOS and GOARCH don't matter for this purpose, this CL
simply clears them on the invocation of the bootstrap toolchain's "go
version".

Fixes #41525.

Otherwise we’d still be writing that we're building cmd/dist
even if GOROOT_BOOTSTRAP we’re wrongly set.

cmd/go: add env -w and env -u to set and unset default env vars

2019-04-23T00:58:08+00:00

Setting environment variables for go command configuration
is too difficult and system-specific. This CL adds go env -w,
to change the default settings more easily, in a portable way.
It also adds go env -u, to unset those changes.

See https://golang.org/design/30411-env for details.

Fixes #30411.

cmd/dist, cmd/link: allow passing default dynamic linker/loader

2019-03-01T06:06:13+00:00

Add an environment variable to make.bash to allow setting the default
dynamic linker/loader. This fixes alpine builds to use
/lib/ld-musl-x86_64.so.1:

  $ readelf -l ../bin/go | grep 'interpreter:' | sed -e 's/^.*interpreter: \(.*\)[]]/\1/'
  /lib/ld-musl-x86_64.so.1

Also re-enable the internal linker tests that were previously disabled
for alpine (CL 41759, CL 41678).

Fixes #18243
Updates #19938

This resurrects CL 50070 authored by Jessie Frazelle.
