Have you provided *linux kernel headers* when building the minimal
gcc?  I had similar (though I don't remember if they were *identical*)
problems when building for ARM, and they were corrected when I povided
kernel heareds to the minimal gcc build. Indeed, it seems that both
"ucontext.h" and a "signal.h" files *are* in the kernel headers.
