    perf config: Add some new -DHAVE_XXX to CFLAGS · 8e2c241f
    Jin Yao authored
    For most of libraries, in perf.config, they are recorded with -DHAVE_XXX in
    CFLAGS according to if the libraries are compiled-in.  Then C code then will
    know if the library is compiled-in or not.
    
    While for glibc, no -DHAVE_GLIBC_SUPPORT exists.
    
    For python and perl libraries, only -DNO_PYTHON and -DNO_LIBPERL exist.
    
    To make the code more consistent, the patch creates -DHAVE_LIBPYTHON_SUPPORT
    and -DHAVE_LIBPERL_SUPPORT if the python and perl libraries are compiled-in.
    
    Since the existing flags -DNO_PYTHON and -DNO_LIBPERL are being used in many
    places in C code, this patch doesn't remove them. In a follow-up patch, we will
    recontruct the C code and then use HAVE_XXX instead.
    
    v3:
    
    Move 'CFLAGS += -DHAVE_LIBPYTHON_SUPPORT' and 'CFLAGS +=
    -DHAVE_LIBPERL_SUPPORT' to other places to avoid duplicated feature checking.
    
    v2:
    
    Create -DHAVE_GLIBC_SUPPORT, -DHAVE_LIBPYTHON_SUPPORT and
    -DHAVE_LIBPERL_SUPPORT.
