[Android] [IL2CPP] Flag --long-plt is missing when building a release build (Error: PLT offset too large, try with --long-plt)
Link error "android-ndk-r16b/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld.gold: error: PLT offset too large, try linking with --long-plt" is shown when building a release build wih 2019.1.0a9" is shown when making a release build with Unity 2019.2.0a9.
This issue only occurs for Android release builds. We are not sure if --long-plt was removed in 2019 or there is a different issue causing the error.
Request: please add a flag --long-plt
Steps:
1. Download and open project from ownCloud (see edit)
2. Switch to Android
3. In menu bar: Build > Select Configuration
4. Choose or make sure it's using Development Bundle
5. Click Code Only
6. Wait 5-60 minutes
Result: After some time building assetbundles, it finally get to the linking phase and will fail showing this message:
android-ndk-r16b/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld.gold: error: PLT offset too large, try linking with --long-plt
Reproduced with: 2019.2.0a9
Not reproduced with: 2020.1.0a25 (due to errors in Console), 2019.3.2f1 (due to errors in Console), 2018.4 and earlier (due to errors in Console)
WORKAROUND: add the following line at the top of BuildCodeAndRun() in AndroidUtils.cs:
PlayerSettings.SetAdditionalIl2CppArgs("--command-log=on --linker-flags=\"-Wl,--long-plt\"");

Also it's can be when you build IL2CPP with build option 'allowDebugging'

Resolution Note:
The workaround of:
PlayerSettings.SetAdditionalIl2CppArgs("--command-log=on --linker-flags=\"-Wl,--long-plt\"");
is the way to do it. Note, that the linker used by Unity depends on Unity version and ARMv7 vs ARM64, the bfd linker does not have --long-plt option.
