Answer 1

The library is the standard C library (libc). This is normally glibc but some embedded linuxes will use musl and Android uses bionic.

Linux as a platform is fairly unique in that the kernel/user interface is rather stable so different c libraries can be used.

libc library will be linked in automatically as a shared library by your toolchain unless you tell it not to.
