+This patch fixes a case where it find crypt defined in libc (musl) but
+not in specified libraries then it ends up assigning
+
+LIBCRYPT="-l" which then goes into makefile cause all sort of problems
+e.g.
+
+ld: cannot find -l-m32
+| collect2: error: ld returned 1 exit status
+
+The reason is that -l appears on commandline with out any library and
+compiler treats the next argument as library name whatever it is.
