This appears to be describing a condition (GCC_NO_EXECUTABLES called under
various possible conditions, via GCC_CHECK_TLS being called under those
conditions) that is neither new after my patch, nor in any way a problem,
so I'm not sure of the point of this warning or why my patch should have
caused it. I have however applied this followup patch to fix a quoting
issue in my patch that perturbs things sufficiently to avoid this warning,
although I do not believe the pre-existing code in this macro is correctly
quoted either (I'd expect the static linking call of AC_RUN_IFELSE to need
to be quoted as an argument to AC_LINK_IFELSE).
