Subject: [PATCH] ftrace: Allow to explicitly disable the build of the dynamic
 ftrace with regs

This patch allows to explicitly disable
CONFIG_DYNAMIC_FTRACE_WITH_REGS. We will need to do so on
PPC with a broken gcc. This situation will be detected at
buildtime and could not be handled by Kbuild automatically.

Wait. Can it be detected at build time? That is, does it cause a build
error? If so, then you can have Kbuild automatically detect this and
set the proper value. We do this with 'asm goto'. There's tricks in the
build system that can change the configs based on if a compiler is
broken or not.

Also it fixes the prompt of DYNAMIC_FTRACE. The uppercase
better fits the style of the other menu entries.

This patch does not change the default value.
