+Subject: core: zlib: fix build warning when _LFS64_LARGEFILE is not defined
+
+In zlib, _LFS64_LARGEFILE is expected to be a boolean directive, either
+1 (true) or 0 (false). Depending on toolchain version and directives
+build may produces warnings (as shown below with gcc 9.3) when the macro
+is not defined hence this change to default it to value 0 (false).
