Among other reasons (listed in answers on -hackers), if you link your programs statically, the parts that you used from external libraries add up to the total size. You can do objdump to see their sizes, and in some cases change the implementation of your program to avoid linking in the most bloated parts, somtimes sacrificing robustness or some unneeded features for the sake of size.
