uselessly wasting cpu cycles trying. Fails when linking binaries with 'relocation truncated to fit: R_PPC_PLTREL24' - jca@ tried to fix ld at some point, or something else has to be whacked. See http://build-failures.rhaalovely.net/powerpc/2017-06-03/devel/llvm.log or http://build-failures.rhaalovely.net/powerpc/2017-04-02/devel/llvm%2C-main.log or the bazillions previous failures.
