You aren't comparing like with like here. Your hello_c is statically
linked with libc, but hello_hs is dynamically linked with libc.
Here's what they look like on my machine:
13220 hello_c dynamically-linked
481503 hello_hs dynamically-linked
1444114 hello_c statically-linked (gcc -static ...)
1958990 hello_hs statically-linked (ghc -optl-static ...)

Ok, point taken. There is a lot of code re-use in both languages.
But because Haskell is higher-level, it tends to re-use the lower-level
C library in addition to its own libraries. That is all.
