After reading your comment, I was about to say the binary is compiled with 
`ppc64le` and requires `host-byteorder-little-endian` but realized the 
`--target=ppc64le-unknown-linux-gnu` is only used with `-emit-llvm`, and the 
`RUN` lines that build executables doesn't specify a target.

Nevertheless, I wonder test coverage for `%clang_pgogen` should be added here 
as well.

Relatedly, I do get compilation errors on ppc big-endian systems for 
`clang_pgogen` in another compiler-rt test 
([commit](https://github.com/llvm/llvm-project/commit/5136c167a2573fbd05179849cb41b198c4862b12)
 and [buildbot link](https://lab.llvm.org/buildbot/#/builders/18/builds/13228)
