The issue here is that the linker binary crated with the gcc-i686-linux- android toolchain contains a .plt section, when it shouldn't.
The consequence is that once you execute a binary that depends on any shared library, the linker will fail when it tries to initialize itself, because it can't contain any .plt section (and in our case it fails when looking for the gdb hook rtld_db_dlactivity). If you compare the linker binary with the one created using the pre- built android toolchain, you can easily see that the elf file doesn't contain the .plt section, not causing any issue.
