No those bits seems to be needed because of a problem in pkg-config
itself. See this nixpkg pkg-config package snippet:

--8<---------------cut here---------------start------------->8---
  configureFlags = [ "--with-internal-glib" ]
    ++ optional (stdenv.isSunOS) [ "--with-libiconv=gnu" "--with-system-library-path" "--with-system-include-path" "CFLAGS=-DENABLE_NLS" ]
       # Can't run these tests while cross-compiling
    ++ optional (stdenv.hostPlatform != stdenv.buildPlatform)
       [ "glib_cv_stack_grows=no"
         "glib_cv_uscore=no"
         "ac_cv_func_posix_getpwuid_r=yes"
         "ac_cv_func_posix_getgrgid_r=yes"
       ];
