[Driver][Linux] Pass --hash-style=gnu to ld unless special cased

To align with many Linux distributions which configure GCC with
--enable-default-hash-style=gnu or binutils with --with-linker-hash-style=gnu.
ld.lld does not support changed default, so passing the option in the driver is
better.

Note: there was a bug that Debian specified both --hash-style=gnu and
--hash-style=both. Actually its GCC has defaulted to --hash-style=gnu since 2007.
