Subject: [PATCH] lmw, lswi and related PowerPC insns aren't allowed on ppc64le
lmw, lswi and related PowerPC insns aren't allowed on ppc64le
Newer binutils produce an error when the assembly contains lmw, stmw,
lswi, lswx, stswi, or stswx instructions in little-endian mode.
Only build and run the lsw and ldst_multiple testcases on ppc64[be].
