Never version of libgcc are built with LSE implementation in mind. To determine if LSE is available on platform it calls __getauxval(), so in some cases we can get undefined reference to __getauxval() error.
Prominent case is libgcc_eh.a library, which is used by C++ TAs. Exception handler depends on atomic operations, so it tries to call init_have_lse_atomics() first. This function in turn calls __getauxval(), which causes linking error.
In the future we can make __getauxval() to return actual platform capabilities.
