Set the default ABI to C for extern blocks and extern functions

Previously, the default ABI was set to Rust, which is not correct for extern blocks and extern functions. This patch changes the default ABI to C for these cases. gcc/rust/ChangeLog: * hir/rust-ast-lower-base.cc (ASTLoweringBase::lower_qualifiers): Change default ABI to C for extern functions (ASTLoweringBase::lower_extern_block): Likewise Signed-off-by: Nobel Singh <[email protected]>
