+on uclibc systems libintl and libuargp are separate from libc.
+so they need to be specified on commandline when we use proxy-libintl
+then libintl is a static archive so it should be listed last since
+elfutils does not respect disable-nls we need to link in libintl
+
+We add a new option --enable-uclibc which will be used to control
+the uclibc specific configurations during build.
