Bug description:
  greenlet 3.0.3 fails to build on riscv64 and ppc64el:

  riscv64-linux-gnu-gcc -Wsign-compare -DNDEBUG -g -fwrapv -O2 -Wall -g
  -fstack-protector-strong -Wformat -Werror=format-security -g -O2 -fno-

  /<>/src/greenlet/greenlet.cpp -o build/temp.linux-
  riscv64-cpython-311/<>/src/greenlet/greenlet.o -Os

  So the reason is that recent Linux distros decided to build with -fno-
  omit-frame-pointer by default. Apparently both the riscv64 and the
  ppc64el implementations cannot cope with that.

  The issue can be reproduce by adding -fno-omit-frame-pointer to the
  build flags.
