This changes adds support to build the autotools if the host installed version is not a suitable version. Autoconf and automake have hard coded references to the install prefix and host tools and this makes it impossible to relocate, that is use in any path other than the install prefix. To bootstrap automake you need to first build a suitable autoconf and with that you can built automake for the install prefix. The other complication is not referencing the install prefix in the path when building in the RSB. Having the install prefix in the path can result in strange issues appearing such as gcc using a new assembler feature not present in an older assember installed under the install prefix. The process is to build the autotools using an install prefix to an internal path inside the RSB temporary path and to use that autoconf to build the version for the install prefix. The internal install prefix version is also used to bootstrap RTEMS.
