feat(nfpm): support arm in termux

[rsteube]

This adds arm support for termux (arch needs to be called arm as well).

---

Ok this drove me nuts, but I think I've got it working now: https://github.com/carapace-sh/carapace-bin/releases/tag/v1.0.3

1. First of all most of the android targets need CGO_ENABLED=1.

2. Then there's the need for a patched runtime due to the /data/data/com.termux/files prefix (adopted from the golang package).

3. Two builds so that for termux the patched gobinary can be used. Then add a termux suffix to the archives for clarity.

builds:
  - id: default
    env:
      - CGO_ENABLED=0
    goos:
      - linux
      - windows
      - darwin
    main: ./cmd/carapace
    binary: carapace
    tags:
      - release
  - id: termux
    env:
      - CGO_ENABLED=1
    goos:
      - android
    goarch:
      - amd64
      - arm64
      - arm
      - "386"
    main: ./cmd/carapace
    binary: carapace
    tags:
      - release
    gobinary: go-termux
archives:
  - name_template: '{{ .ProjectName }}_{{ .Os }}_{{ .Arch }}{{ if .Arm }}v{{ .Arm }}{{ end }}'
    builds:
     - default
    format_overrides:
      - goos: windows
        format: zip
  - id: termux
    builds:
      - termux
    name_template: '{{ .ProjectName }}_{{ .Os }}_{{ .Arch }}{{ if .Arm }}v{{ .Arm }}{{ end }}.termux'

4. Compiling needs the Android NDK with the CC environment variable set. I used a script for this (/usr/local/bin/go-termux).

#!/bin/bash

bindir="/opt/android-sdk/ndk/${NDK_VERSION}/toolchains/llvm/prebuilt/linux-x86_64/bin"
[ "$GOARCH" = "amd64" ] && export CC="$bindir/x86_64-linux-android${ANDROID_VERSION}-clang"
[ "$GOARCH" = "arm64" ] && export CC="$bindir/aarch64-linux-android${ANDROID_VERSION}-clang"
[ "$GOARCH" = "arm" ] && export CC="$bindir/armv7a-linux-androideabi${ANDROID_VERSION}-clang"
[ "$GOARCH" = "386" ] && export CC="$bindir/i686-linux-android${ANDROID_VERSION}-clang"

exec /usr/local/go-termux/bin/go "$@"

5. There's termux-apt-repo which makes repo creation pretty easy with gh_pages. Just needs a fix as goreleaser uses data.tar.gz.

awesome, thank you!

@rsteube what about /etc/resolv.conf ? its not present in bindir

[aicynide]

@rsteube you are completely wrong, have you test yourself in termux? also, read the termux docs, TERMUX_PREFIX is /data/data/com.termux/files/usr not /data/data/com.termux/files

what's this?

@aicynide I appreciate your participation in this, but your tone is slightly off.

[caarlos0]

@aicynide your tone is very off in this, let's be more civil in the next interactions, please.

FWIW we have a CoC: https://github.com/goreleaser/goreleaser?tab=coc-ov-file#readme
