Alyssa Ross 4f80464645 Apply OS checks to host platform, not build Previously, the build system used uname(1) output when it wanted to check the operating system it was being built for, which meant that it didn't take into-account cross-compilation when the build and host operating systems were different. To fix this, instead of consulting uname output, we consult the host triple, specifically the third "kernel" part. For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a simple ifeq to test whether we're compiling for that system, but for other platforms, like Darwin, FreeBSD, or Solaris, we have to use a more complicated check to take into account the version numbers at the end of the "kernel"s. I couldn't find a way to just strip these version numbers in GNU Make without shelling out, which would be even more ugly IMO. Because these checks differ between kernels, and the patsubst ones are quite fiddly, I've added variables for each host OS we might want to check to make them easier to reuse.		2021-06-23 15:00:36 +00:00
