These changes allow for Blink and Blinkenlights to be compiled for MacOS PowerPC hosts, tested on MacOS Tiger 10.4. Due to its legacy nature, the Tiger build was done with MacPorts GCC 14 and legacy-support-devel. Major changes include working around a missing F_DUPD_CLOEXEC macro with two fcntls; including sys/types.h before netinet/udp.h; adding detection for the __ppc__ macro for cpuid purposes; and ensuring feature flags are properly matched to ensure mkfifo does not turn on mkfifoat.

In fact, this patch fixes the build on any macOS below 10.7. |

@bjia56 Do you have a Cygwin environment handy to fix the build / headers issue? |

Not locally, but I can spin one up in a virtual environment. |
