It's perfectly reasonable to want to avoid building the tcg code

Why? It doesn't do any harm to have extra code.
It's half a megabyte of code.
And half a day to compile ;)
Also, it's better not to have code
snippets that call mprotect(PROT_EXEC) in your executable.
I agree, is there any reason not to enable compiling less into the binary?
There are folks interested in eliminating as much as possible to reduce
the attack surface and auditing requirements, for example.
It's not a bad idea, it's just that what --disable-cpu-emulation does is
evil. Being that I wrote the implementation, I'm quite confident in
declare it as such :-)
It was initially a work around in the dyngen days because a GCC 3.x
compiler wasn't available for PPC 44x easily. It's always been the
wrong approach to addressing the problem though and since we don't have
weird compiler dependencies anymore we really should remove it.
