[BUG] neither ndk-build nor CMake toolchain file uses --gc-sections for shared libraries by default #1717
Description
Description
Neither ndk-build nor CMake toolchain file uses --gc-sections for shared libraries by default (they both do for executables). This is contrary to our own docs: https://android.googlesource.com/platform/ndk/+/master/docs/BuildSystemMaintainers.md#Controlling-Binary-Size
This seems to have always been the case (checking all the way back to r10 shows the same behavior). I'm not sure if the author back then did that intentionally or if it was an oversight, but afaik there's no downside to using this flag, so it should be on by default.
