Issue With "Nothing to be done for ..."

[beneficii@gmail.com]

(I'm using Mac OS X, the latest version 10.something.5.)  Well, I
don't really understand this message, but I keep getting this error
when I use "make" to try to compile FCEU:

Basically, I get just this output:

Making all in src
make[1]: Nothing to be done for `all'.
make[1]: Nothing to be done for `all-am'.

I do not understand the meaning of it, and in a search of GNU's
website I have found no information on it.  It SEEMS to cause the
linking to fail, but I don't understand it.  What can I do to resolve
this issue?
