[Bug target/68028] Compilation error "lto1: error: target attribute or pragma changes single precision floating point", with "-flto" on different variant of powerpc like -mcpu=e6500, 8540, 8548, e500mc, e500mc64, e5500. With gcc-5.2.0 while with 4.9.3 it is working fine.

Hi Richard,

There are the changes came after gcc-4.9.3 because of that I am getting above
issue, but if I comment these 2 line in file (tree-streamer-in.c &
tree-streamer-out.c) then it resolves the issue I am facing in gcc-5.2.0.

Because of these changes,  the gcc-5.2.0 fails but gcc-4.9.3 sources are
working fine.
