I don't think that the wording is correct because -mabi=elfv1 and
-mabi=elfv2 are "options" for either endian.

Delete the second line and replace it with something like
"This is the default ABI for big-endian PowerPC 64-bit Linux.
Overriding the default ABI requires special system support and is
likely to fail in spectacular ways."

Similarly, delete the second line and replace it with something like
"This is the default ABI for little-endian PowerPC 64-bit Linux.
Overriding the default ABI requires special system support and is
likely to fail in spectacular ways."
