[Rpm-maint] AArch64 support

[Mark Salter]

Here is a patch which adds support for AArch64 architecture. This is
just basic support and further support (i.e. auxv parsing) may be desired.
It is pretty straightforward except for the hunk in installplatform which
sets LIB=${LIB}64. The existing test does this for linux and CANONCOLOR 3.
Aarch64 is CANONCOLOR 2, but still wants to use lib64 for the libdir.
