bisect-runner.pl can now build all revisions on sparc64 Linux.

test_prep back to 5.001n, miniperl back to 5.000, for both 32 and 64 bit.
This requires backporting tweaks to the Linux hints file, and patching
early Configure to detect byteorder correctly as 87654321 when using
linker flags to build 64 bit.
