+Description: Allow clearing OPENSSLDIR/ENGINESDIR/MODULESDIR from final binary
+ When building with OPENSSL_CLEAR_DIRINFO=1, the directory path defines
+ (OPENSSLDIR, ENGINESDIR, MODULESDIR) are set to empty strings, preventing
+ build-time path information from being embedded in the final binary.
+ Additionally, -I include paths and non-deterministic compiler flags
+ (-ffile-prefix-map, -fdebug-prefix-map, -fmacro-prefix-map) are stripped
+ from the recorded compiler flags in buildinf.h.
