Allow enabling frame pointer support; this makes it easier to hook into the various kernel features that claim they require it without having to add Kconfig conditionals everywhere (a la mips, ppc, s390, and microblaze). When enabled, it basically eliminates leaf functions as such, and stops optimizing tail and sibling calls. It adds around 3% to the size of the kernel when enabled.
