Drop -D_FILE_OFFSET_BITS=64 support for now 32-bit android uses 32-bit off_t by default. When building with -D_FILE_OFFSET_BITS=64 with unified headers off_t are promoted to 64-bit, but there are bugs in the toolchain and spotty support for it in the platform (not all functions are available until android-24, and the platform zlib is compiled with 32-bit off_t). Also, unless every library&program is rebuilt with 64-bit off_t, including user-built ones, we risk a mismatch between programs and libraries which can cause serious (but sometimes subtle) runtime failures. As -D_FILE_OFFSET_BITS=64 is not that important for most users (with mariadb requiring it as an exception), we drop the support for now by patching it away in <sys/cdefs.h>.
