This PR fixes issue #7916
to build for aarch64 the cmake variable ``-DCMAKE_HOST=aarch64-linux-gnu``
should be passed that
is in turn propagated to the autotools (configure step) for libbacktrace.
````bash
cmake .. \
-DCMAKE_SYSTEM_NAME=Linux \
-DCMAKE_SYSTEM_VERSION=1 \
-DCMAKE_C_COMPILER=/usr/bin/aarch64-linux-gnu-gcc-8 \
-DCMAKE_CXX_COMPILER=/usr/bin/aarch64-linux-gnu-g++-8 \
-DCMAKE_FIND_ROOT_PATH=/usr/aarch64-linux-gnu \
-DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER \
-DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY \
-DCMAKE_HOST=aarch64-linux-gnu
````
I tested this to build the runtime for ``aarch64`` and ``riscv64``, the
runtime ``.so`` was produced in both
cases with no errors displayed during the build.
