Better explanation for missing static C library

Until now, the explanation for a missing static C library didn't actually
guide the users to look above and see the error message! So with this
commit, I edited it a little to be more clear (and mention to look
above). Also, I noticed that on Amazon AWS systems, the static C library is
installed as a separate package, so to help the users, I added the
necessary command and some better explanation.

+The 'sys/cdefs.h' headaer cannot be included, or a usable static C library
+('libc.a', in any directory) cannot be used with the current settings of
+this system. SEE THE ERROR MESSAGE ABOVE.
+
+Because of this, we can't build GCC. You either 1) don't have them, or 2)
+the default system environment aren't enough to find them.
+
+1) If you don't have them, your operating system provides them as separate
+packages that you must manually install. Please look into your operating
+system documentation or contact someone familiar with it. For example on
+some Redhat-based GNU/Linux distributions, the static C library package can
+be installed with this command:
+
+    $ sudo yum install glibc-static
+
+2) If you have 'libc.a' and `sys/cdefs.h', but in a non-standard location (for
+example in '/PATH/TO/STATIC/LIBC/libc.a' and
+'/PATH/TO/SYS/CDEFS_H/sys/cdefs.h'), please run the commands below, then
+re-configure the project to fix this problem.
+
+    $ export LDFLAGS="-L/PATH/TO/STATIC/LIBC \$LDFLAGS"
+    $ export CPPFLAGS="-I/PATH/TO/SYS/CDEFS_H \$LDFLAGS"
