+From df2cd898e48208f26320d40c3ed6b19c75c27142 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] libtool: Fix support for NIOS2 processor
+
+The name of the system contains the string "nios2". This string
+is caught by the some of the greedy checks for OS/2 in libtool,
+in particular the *os2* branches of switch statements match for
+the nios2 string, which results in incorrect behavior of libtool.
+
+This patch adds an explicit check for *nios2* before the *os2*
+checks to prevent the OS/2 check incorrectly trapping the nios2
+as well.
