I think those instructions are rather old. Two things:

* usually, GCC build instructions say not to make the build directory a
  subdirectory of the source
* nowadays you don't need to --disable-libada and then "make -C gcc
  gnatlib gnattools"

What compiler are you starting from?

What stage of the build did this fail at? (stage_current in the build
directory)

It looks as though this is to do with "Native Language Support (NLS),
which lets GCC output diagnostics in languages other than American
English". The configuration documentation at
https://gcc.gnu.org/install/configure.html suggests --disable-nls (which
is what I do) or --with-included-gettext.
