glibc: Drop ppc sqrt optimisations
OpenEmbedded isn't an upstream or a patch repository. These are optimisations which for reasons unknown were never merged into upstream glibc. We have no active ppc maintainers and these patches are at an evolutionary dead end. Since they are optimisations, there may be small performance regressions by removing them but OE can't carry patches like this indefinitely and these appear to have no future.
