Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Don't add a new FTS_LIBS variable but prepend libraries to LDLIBS
   instead of appending them

+Subject: [PATCH] Fix static linking with musl-fts
+
+Don't append libraries to LDLIBS but prepend them in cpuset_lib/Makefile
+and cpuset/Makefile.inc to allow the user to provide its FTS library
+such as -lfts for musl/uclibc through LDLIBS
+
+This will fix static build of ltp with musl-fts on uclibc
