Made GCC v4.8.2 build on ARM using the patched PKGBUILD.

libtool needs to be uninstalled to install the new GCC v4.8.2.  I tried building libtool but it failed on a test.  I am talking to GNU about that and they say to 1) use http://alpha.gnu.org/gnu/libtool/libtool-2.4.2.418.tar.gz, 2) wait for the next release of Libtool, which is underway.
