+ Use direct accesses for external data symbols. It avoids a GOT indirection

is

:option:`-s

Add a new option -mdirect-extern-access similar to other targets. This removes
GOT indirections on external symbols with -fPIE, resulting in significantly
better code quality. With -fPIC it only affects protected symbols, allowing
for more efficient shared libraries which can be linked with stand
