New description:

 The executables inside the GHC binary tarball seem to come with debug
 information. Stripping it noticeably reduces the binary sizes:

 {{{
 $ file /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc
 /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc: ELF 32-bit LSB executable, Intel
 80386, version 1 (SYSV), dynamically linked (uses shared libs), for
 GNU/Linux 2.6.26,
 BuildID[sha1]=0x6012a4c86cd3f410ca0e59ab4ac872ce740d03c6, not stripped

 $ du -sh /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc
 1,4M    /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc

 $ strip -s /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc

 $ du -sh /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc
 1021K   /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/ghc

 $ du -sh /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/haddock
 3,2M    /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/haddock

 $ strip -s /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/haddock

 $ du -sh /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/haddock
 2,3M    /path/to/ghc-7.8.2/lib/ghc-7.8.2/bin/haddock
 }}}

 Do we really need to include the debug info for exes?

Comment:

 The binaries from https://launchpad.net/~hvr/+archive/ubuntu/ghc are
 stripped however.
