buildsystem: fix build errors for x86 on OSX

Browse source 
Define _NLS_PRIVATE in tools/llvm-tblgen/Makefile so that
<tools/compat/nl_types.h> will pull in <include/nl_types.h>. This is
necessary as Clang's c++/v1/locale implementation contains references
to catopen and other catalog symbols that aren't defined anywhere.
Moreover, the compiler will complain about NL_CAT_LOCALE not being
declared. The compat nl_types.h fixes these discrepancies.

However, <nl_types.h> uses __format_arg to add function attributes to
declarations. On NetBSD __format_arg(fmtarg) is defined by
<sys/cdefs.h> to be __attribute__((__format_arg__ (fmtarg))) for
briefness, but other platforms don't do that. Consequently, the build
will fail on catopen and friends function declarations because the
compiler doesn't know how to handle __format_arg(fmtarg). A fixup to
<tools/compat/nl_types.h> takes care of this, but it won't win any
beauty contest.
