Add GCC 8 recipes

This changeset is including the review feedback from last patchset

V3:

- Drop wholesale change of ARM tune files
- Fix gcc/libatomic by disabling ifuncs for libatomic
to avoid march/mtune incompatiblity on armv7+, (thanks Andre for working on it)
- Keep valgrind patches

V2:

- Fixes ppc such that we dont have to change machine options so it remains backward compatible and folks can still use gcc7
- Tweaks arm tunes to set -mtune instead of -mcpu, this avoids conflicts between -march/-mcpu
- Removes workarounds to avoid these conflicts in valgrind
- Add mips 74kc tune files
- Linux yocto changes are also part of Bruce's kernel updates but this makes it complete until those changes are pulled in

The following changes since commit 23f15c63777020f5d43b070a1eb2bcf246c19ff8:

rpm: Fix patch to ensure variables aren't used uninitialised (2018-06-07 08:52:13 +0100)
