Linux command "file" shows "for GNU / Linux 2.6.24"

I always use the command fileto check the file type, mainly after compiling a new project, to make sure everything is in order.

The result looks something like this:

proj_out: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.24, BuildID[sha1]=0x23d9f966854e09d721c6110d505247483dae02fe, stripped

My question is that my Linux kernel has been updated to version 3.0+, why does it still show that it compiled for older versions of Linux?

for GNU/Linux 2.6.24

Is this related to the team fileor do I need to do something to compile my project with the new Linux kernel?

thank
