app-benchmarks/iozone: append CPPFLAGS to CFLAGS In non-parallel builds, make executes rules in the order they are defined in the makefile; In parallel builds, if no explicit rule is defined for a target, make uses the default implicit rule instead. Both CFLAGS & CPPFLAGS will be used in default ".c.o" rule. The makefile of iozone doesn't use CPPFLAGS anywhere. So append all necessary flags to CFLAGS is a quick solution to handle both parallel and non-parallel build. For x86 platforms, "-D_FILE_OFFSET_BITS=64" is required. Without it, off_t defaults to 32-bit, causing build failures with errors like "conflicting types for 'pwrite64'". Closes: https://bugs.gentoo.org/947708 Signed-off-by: Z.
