+Subject: [PATCH] Add cross-platform build ability
+
+Currently it is not possible to build psutil on MacOS for Linux
+target using external toolchain. It fails due to build script
+detects build host OS and changes build logic according to detected
+OS.
+
+This patch allows to redefine os.name and sys.platform using ENV
+vars TARGET_OS_NAME and TARGET_SYS_PLATFORM. If these variables
+are not defined then os.name and sys.platform is used as it does
+currently.
+
+Using this patch it is possible to compile psutil on MacOS with
+OpenWrt GCC Toolchain (OpenWrt is Linux).
