-Subject: [PATCH 07/12] libtool: Fix support for NIOS2 processor
+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.
+Switch to use $host_os instead of $host and tweak the patterns to
+match to avoid this problem for nios2.
