Thomas reported that make PYTHON=python2 is not work on some systems. I can reproduce it on my ArchLinux box too. This is because it's overridden by config/feature-checks/Makefile regardless of PYTHON setting. I guess it's a bug slipped into during the feature checking change. Actually, we don't need to check python-config in the feature-checks. We can just pass appropriate FEATURE_CHECK_*FLAGS.

由 Mark Rutland 提交于
Currently the feature-checks Makefile does not inherit $(CC), and calls cc rather than $(CROSS_COMPILE)gcc. Thus the feature checks invoke the native toolchain rather than the cross toolchain, and can identify features as available when they are not. This can break the build. Additionally the native pkg-config is always called as opposed to $(CROSS_COMPILE)pkg-config, so the wrong flags and paths may be passed to the cross compiler. This patch passes CROSS_COMPILE down to the feature-checks Makefile, and forces its use. Additionally pkg-config is replaced with $(CROSS_COMPILE)pkg-config via a new $(PKG_CONFIG) variable. This patch has been build tested on x86_64 and arm.
