### build
Cross compilation is now supported with an extra configure option:
`./configure --target-arch=aarm64`
Preliminary support for cross compilation is now available. Targeting an older
CPU on the same architecture using your native compiler can be accomplished by
using the `--target-arch` option to `configure` as follows:
Additionally, a prefix to the toolchain can be provided to automatically set up
CC and CXX:
`./configure --target-arch=aarm64 --cross-prefix=aarch64-linux-gnu`
~~~
./configure --target-arch=broadwell
~~~
Additionally, some support for cross-compiling to other architectures has been
added via the `--cross-prefix` argument to `configure`. To cross-compile, set CC
and CXX to the cross compilers, then run configure as follows:
~~~
./configure --target-arch=aarm64 --cross-prefix=aarch64-linux-gnu
~~~
