| |
This patch checks the values passed by CFLAGS (-DHAVE_XXX) and then print the status of libraries.
For example, if HAVE_DWARF_SUPPORT is defined, that means the library "dwarf" is compiled-in. The patch will print the status "on" for this library otherwise print the status "OFF".
v2: --- 1. Use IS_BUILTIN macro to replace #ifdef/#endif block.
2. Print color for on/OFF.
