+Subject: [PATCH] m4: fix detection of atomics
+
+In cross-compilation, it is impossible to run code at configure time to
+detect the target specifics.
+
+As such, AC_TRY_RUN fails miserably to detect reliably that atomic
+intrisics are present in a toolchain, and decides they are not just
+because this is cross-compilation.
+
+Instead of AC_TRY_RUN, use AC_LINK_IFELSE that does not need to actually
+run code, since all we're interested in is whether the intrisics are
+present (or not). Fix both the 32- and 64-bit variants, even if the
+latter is not used currently.
+
+Fixes build failures detected by the Buildroot autobuilders, like:
+    http://autobuild.buildroot.org/results/23a/23ac0e742ed3a70ae4d038f8c9eadc23e708f671/build-end.log
+    http://autobuild.buildroot.org/results/192/1923d0b570adba494f83747a9610ea6ec35f5223/build-end.log
+
+and many other cases, espcially on architectures where such intrisics are
+present, but where the toolchain does not have threads (and anyway, it
+is much more efficient to use the intrisics rather than use mutexes).
