// Code defined in LIBC_NAMESPACE should use `_ld_abi` without qualifier so it
// gets LIBC_NAMESPACE::_ld_abi as declared here.  In a production libc, this
// is just a namespace alias for ld::abi::_ld_abi (which has an `extern "C"`
// linkage name).  In the unittest build, this is a constexpr reference to the
// ld::testing mock-up for the test binary's startup modules.
