export.h: allow for per-symbol configurable EXPORT_SYMBOL()
Similar to include/generated/autoconf.h, include/generated/autoksyms.h will contain a list of defines for each EXPORT_SYMBOL() that we want active. The format is: #define __KSYM_<symbol_name> 1 This list will be auto-generated with another patch. For now we only include the preprocessor magic to automatically create or omit the corresponding struct kernel_symbol declaration. Given the content of include/generated/autoksyms.h may not be known in advance, an empty file is created early on to let the build proceed.
