WIP on webkit2 for PowerPC

Description
I have finally built all major dependencies for webkit2-gtk and rewritten existing patches for @2.36.0. However, unsurprisingly, once I sorted out all configure errors, the build did not proceed much further :)
Any idea why Cmake fails to identify the arch?

Here is the source code:
namespace WTF {
#if OS(DARWIN)
#if CPU(X86)
typedef i386_thread_state_t PlatformRegisters;
#elif CPU(X86_64)
typedef x86_thread_state64_t PlatformRegisters;
#elif CPU(PPC)
typedef ppc_thread_state_t PlatformRegisters;
#elif CPU(PPC64)
typedef ppc_thread_state64_t PlatformRegisters;
#elif CPU(ARM)
typedef arm_thread_state_t PlatformRegisters;
#elif CPU(ARM64)
typedef arm_thread_state64_t PlatformRegisters;
#else
#error Unknown Architecture
#endif
inline PlatformRegisters& registersFromUContext(ucontext_t* ucontext)
{
return ucontext->uc_mcontext->__ss;
}
#elif OS(WINDOWS)
using PlatformRegisters = CONTEXT;
#elif HAVE(MACHINE_CONTEXT)
struct PlatformRegisters {
mcontext_t machineContext;
};
inline PlatformRegisters& registersFromUContext(ucontext_t* ucontext)
{
#if OS(OPENBSD)
return *bitwise_cast<PlatformRegisters*>(ucontext);
#elif CPU(PPC)
return *bitwise_cast<PlatformRegisters*>(ucontext->uc_mcontext.uc_regs);
#else
return *bitwise_cast<PlatformRegisters*>(&ucontext->uc_mcontext);
#endif
}
#else
struct PlatformRegisters {
void* stackPointer;
};
#endif
} // namespace WTF
I also tried to specify the arch directly in configure.args, it made no effect. (Argument does get passed to Cmake, but the same error occurs.) From what I can see, no patches were applied to this header file (explicitly, I did not add PPC there, it is there in the source code).
- S. I no one objects, we may keep this ticket as a track record and invitation to participate. If no one joins in, I will slowly post updates from my end.

"Heroes die young, everyone else fails to compile webkit2-gtk on PowerPC." @kencu and I separately undertook this project with limited results. I think Ken got something working on Leopard at one point, but the browser was too slow to be usable. After many days of effort I was unable to get the port to compile on Tiger. Here was my latest public attempt:
https://github.com/macports/macports-ports/pull/12009
I have some more private patches in that direction but I really don't recommend pursuing this. There be dragons of all species. I think time and energy is better spent making webkit2-gtk an optional dependency wherever it is currently required.

Thank you for the reference! Yes, it sounds like a no-go. The only advantage now is better compilers, but I guess that's not the main problem.
I was hoping to get something WebKit-based working, since I am not a fan of FF, and anyway it is dead. On the other hand, both apps for secure web, Tor and i2pd, use FF front-end.
