+configure.ac: Verify that the Loongson MMI code can link
+
+The Loongson MMI code modifies -march and as a result it breaks linking
+when the rest of the code is built with a different -match/-mtune.
+This patch fixes the problem by trying to link the code instead of just
+compiling it. This patch is already committed upstream.

+Subject: Use AC_LINK_IFELSE to check if the Loongson MMI code can link
+
+The Loongson code is compiled with -march=loongson2f to enable the MMI
+instructions, but binutils refuses to link object code compiled with
+different -march settings, leading to link failures later in the
+compile. This avoids that problem by checking if we can link code
+compiled for Loongson.
