There are no top Makefile targets for you to do this and building targets directly from Makefiles in subdirectories often runs into issues (e.g. missing headers that haven't been copied or paths/vars set incorrectly since they are supposed to be set by parent Makefiles). In addition, the errno/reentrant mechanisms used by libm.a are supplied by libc.a. -- Jeff J.
