ace-of-penguins fails to cross build from source, because it confuses
build architecture and host architecture compiler flags. This happens at
the upstream level already. It hasn't been a problem earlier, but now
with PAC/BTI arm64 and amd64 have architecture-specific default flags
that happen to not work on other architectures. I suggest that you move
to AX_PROG_CC_FOR_BUILD from autoconf-archive instead of reinventing the
wheel here and attach a patch for your convenience.
