aarch64: Allow purecap default ABI
This patch allows building a purecap only gcc. To make the default ABI
purecap, configure gcc as
--disable-multilib --with-abi=purecap --with-arch=morello+c64
or
--with-multilib-list=purecap --with-arch=morello+c64
To build a gcc that defaults to lp64 ABI, but supports purecap too use
--with-multilib-list=lp64,purecap
