g++.dg/opt/devirt2.C was failing for mips64-linux-gnu because each
call to xyzzy was accompanied by a R_MIPS_JALR .reloc statement that
also mentioned xyzzy.
This wouldn't happen if the compiler was built to use PLTs by default,
so rather than look for 4 copies of xyzzy, it seemed better to add
-mno-abicalls.
Tested on mips64-linux-gnu and applied.
