attr: build fix for GCC < 4.5

GCC 4.4 and before do not support a message associated to the
"deprecated" gcc attribute. Since such messages are not that useful in
the context of Buildroot, this commit adds a patch that removes them
in the attr source code.

+Subject: [PATCH] Remove messages in "deprecated" gcc attributes
+
+GCC versions up through 4.4.7 (which is used in RHEL 6) do not accept
+any argument for the deprecated attribute. GCC 4.5 and later say the
+"msg" argument is optional. We don't need the messages during
+Buildroot builds anyways.
