attr: build fix for GCC < 4.5

Browse Source 
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.
