The ebuild is (mostly) just a wrapper for preceding software installation 
tools, like make and gcc.

In a previous message you showed us that the Gtypist devs had asked you "Can 
you check whether this appears when running ./configure? Also, which arguments 
are used for ./configure?"

In the case of the nls USE flag, the ebuild is just calling configure with 
certain arguments:

   src_configure() {
       econf $(use_enable nls)
   }
   
   src_install() {
       emake DESTDIR="${D}" install
   }
   
   Note the IUSE variable. This lists all (non-special) use flags that are
   used by the ebuild. This is used for the emerge -pv output, amongst
   other things.
   
   The package's ./configure script takes the usual --enable-nls or
   --disable-nls argument. We use the use_enable utility function to
   generate this automatically, depending on the user's USE flags (see
   Query Functions Reference).

This is a top google hit for use_enable:
