>Description:
If $(LIMITS_H_TEST) is true, then the built <limits.h>
references "syslimits.h".  This test checks
$(SYSTEM_HEADER_DIR), which is /usr/include in a typical
host-x-host build (building a native compiler for a different
target).

Syslimits.h is only installed if fixincludes is run, which
it is not for host-x-host builds; it's explicitly disabled:

# And these apply if build != host.
if test x$build != x$host
then
...
    STMP_FIXINC=
...
fi

$(LIMITS_H_TEST) is a bit bogus anyway.

This is a regression from 2.95, where fixinc was run
regardless, and thus "syslimits.h" was installed.
