Build fails on Solaris 10 due to missing ranlib
Hello, On Solaris 10 and GHC HEAD I get this compilation failure:

Configuring Cabal-1.18.1.3...
ghc-cabal: Cannot find the program 'ranlib' at ':' or on the path
gmake[1]: *** [libraries/Cabal/Cabal/dist-boot/package-data.mk] Error 1the reason for this failure is that in configure.ac we're using FP_PROG_AR_NEEDS_RANLIB which is defined in aclocal.m4 and uses AC_PROG_RANLIB in its body. The problem is that if ranlib is not found then AC_PROG_RANLIB sets RANLIB variable to :' which is preferred way of no-op in POSIX shell even slightly more preferable than setting it to true (google for it if you care). Anyway, ghc-cabal tries to execute :', but this fails since this is shell built-in and not the program/application on the target OS.
The fix should be easy, test if RANLIB is set to `:' and set it to true. This works since true is actually a program/application on Solaris 10:
{{{
$ which true
/usr/bin/true
}}}
Please note that such failure will happen on all OSes (Unix(-like)) which do not provide ranlib command. Also please note that Solaris 11 is not hit by this issue since it provides ranlib in a form of shell wrapper actually calling just `exit 0'
