v2.26.8: fix acarsdec build failure on macOS (#187)

HOST_NAME_MAX is Linux-specific and undefined on macOS, causing 3
compile errors in acarsdec.c. Now patched with #define HOST_NAME_MAX 255
before building. Also fixed deprecated -Ofast flag on all macOS archs
(was only patched for arm64).

+### Fixed
+- **acarsdec build failure on macOS** — `HOST_NAME_MAX` is Linux-specific (`<limits.h>`) and undefined on macOS, causing 3 compile errors in `acarsdec.c`. Now patched with `#define HOST_NAME_MAX 255` before building. Also fixed deprecated `-Ofast` flag warning on all macOS architectures (was only patched for arm64). (#187)

+## [2.26.7] - 2026-03-14
+
+### Fixed
+- **Health check SDR detection on macOS** — `timeout` (GNU coreutils) is not available on macOS, causing `rtl_test` to silently fail and report "No RTL-SDR device found" even when one is connected. Now tries `timeout`, then `gtimeout` (Homebrew coreutils), then falls back to a background process with manual kill. (#188)
