From abbc0761fa0349d49b10dc8c0f10af6bc0578c40 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] gcc10 arm64 build needs __getauxval for linking with
libgcc
Provide a new library libgcc-sup-<platform>.a that contains symbols
needed by libgcc. This needs to be linked after -lgcc to provide
any symbols missing which would normally be provided by glibc.
At the moment this only provides __getauxval on arm64 linux.
