msi: Use -fno-builtin to avoid warnings with gcc 4.1.1.

[Mike McCormack]

gcc 4.1.1 seems to have a bug or some new "feature" in that it still 
warns about builtin iswalpha, etc having a different prototype to the 
msvcrt functions with the same name, even when -fno-builtin-iswalpha is 
specified.

It seems to behave when -fno-builtin is specified though, so I suggest 
we change to using that.
