Subject: [PATCH 1/1] Allow aarch64-linux-gcc to compile bare metal lib

Newlib build system determines the target (i.e. Linux, BSD, bare metal,
etc.) according to the toolchain triplet. This patch changes the
configure script to treat the aarch64-linux-gnu and the
aarch64-linux-musl triplets as bare-metal compilers.
