Fix spurious define in openblas_config.h

TARGET as specified with make is already return-terminated when getarch reads it. This led to an empty line written to config_last.h that awk in Makefile.install then expanded to a spurious "#define OPENBLAS_" in openblas_config.h (as noted by "kmb" on the mailing list)
