Explicitly fail if macOS universal build is attempted #86

Closed bgilbert closed 3 months ago

bgilbert commented 3 months ago

Certain Meson compiler checks fail if CFLAGS has -arch x86_64 -arch arm64. This was causing us not to set HAVE_UNISTD_H, and then to fail the build on an implicit function declaration. Detect this configuration during setup and fail with a clearer error.
