Well, I thought this patch would work for me, but it does not. It looks
like gcc_no_link is set to 'no' on my target because, technically, I can
link even if I don't use a linker script. I just can't find any
functions.
In which case gating on gcc_no_link could be replaced with a test that
looks to see if we can link with the library. Perhaps looking for
exit() or some such that might reasonably be expected to be present.
For example:
AC_CHECK_FUNC(exit)
if test "x${with_newlib}" = "xyes" -a "x${ac_cv_func_exit}" = "xno"; then

* configure.ac (AC_CHECK_FUNCS_ONCE): Add for exit() then make
existing AC_CHECK_FUNCS_ONCE dependent on outcome.
