    perf: tools: Fix cross building · a8a5cd8b
    Mark Rutland authored
    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.
