[PATCH] Fix formatting and wording of llvm-ranlib error message

[Yung, Douglas via llvm-commits]

When llvm-ranlib is run without arguments, it prints out the following error message:

llvm-ranlib.exe: llvm-ranlib.exetakes just one archive as argument

My patch fixes this up a little by adding a space between the "llvm-ranlib.exe" and "takes", as well as adds the word "an" between the words "an" and "argument". With my patch, the error message would look like this:

llvm-ranlib.exe: llvm-ranlib.exe takes just one archive as an argument

This change is NFC.

Here is the simple patch:
