[Bug target/115800] PowerPC GCC cannot build a little endian compile if --with-cpu=power5 is used
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115800 --- Comment #7 from Andreas Schwab --- It is generally assumed that powerpc64le-*-* implies POWER7+ (glibc even requires POWER8+). This is independent of the older -mlittle support (which doesn't have a separate config triple).

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115800 --- Comment #6 from Michael Meissner --- Of course it would also apply if you are building a BE compiler that has little endian multilibs, you would run into the same situation.

It should work no matter what is the default. powerpc64le-* of course, I cannot type.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115800 --- Comment #1 from Segher Boessenkool --- "If you build a little-endian compiler". What does that mean? A cpu=powerpc76le* compiler? Or something else? Note that *any* compiler can be used as little-endian, by just using -mlittle. Nothing more, nothing less. It should work no matter what is the default.
