--disable-nls broken for Solaris 2.8

[Jay A. St. Pierre]

On Solaris 8, if I try to do this:

  tar xvzf gawk-3.1.1.tar.gz
  cd gawk-3.1.1
  ./configure --disable-nls
  make

It looks like it still tries to do something with nls.  In any 
case, it doesn't compile properly:

make 'CFLAGS=-g -O2' 'LDFLAGS=' all-recursive

I haven't figured out how to fix this, so I will just build with 
NLS enabled.
