baggage...

+Subject: [PATCH] configure: fix build on mips
+
+This patch is a historical baggage that Buildroot has carried for ages
+(since 2006), and the reason for it are notentirely clear.
+
+Since dmalloc is pretty tricky, and as this patch has not been
+identified as causing issues, we keep it; we just add the configure.ac
+patchlet to match the one in configure.
+
+As for the title, the original patch was named dmalloc-mips.patch, so
+presumably it fixes some mips issue; let's title the commit that way.
