+On hosts with FORTIFY_SOURCES, stringize support is required, as it's used by
+the macros to wrap functions (e.g. read and open in unistd.h). Those wrappers
+use the STRING() macro from unistd.h. A header in the bash sources overrides
+the unistd.h macro to 'x' when HAVE_STRINGIZE is not defined, causing the
+wrappers to generate calls to 'xread' and 'xopen', which do not exist,
+resulting in a failure to link.
+Assume we have stringize support when cross-compiling, which works around the
+It may be best for upstream to either give up on supporting compilers without
+stringize support, or to not define STRING() at all when FORTIFY_SOURCES is
+defined, letting the unistd.h one be used, instead.
