Yeah, you're right: I patched GMP because I first tried to build the
toolchain on aarch64-mac. Both patches were definitely needed for that.

Karel Gardas just submitted patches this morning to upgrade expat to

A couple of months ago, I was able to build an RTEMS toolchain on
aarch64 Linux with just an expat upgrade. I was not aware that GMP was
needed as well.

When following the quick-start guide, I was stuck in Install Tool
Suite procedure. Using this command:

I can't help you fix this, but I've successfully built 6/rtems-arm tools
+ BSP on a M1 Mac using multipass. basically:
1) create the ubuntu VM: "multipass launch -n u2004 -c 6 -d 16G -m 4G
20.04"
2) create a shared folder: "multipass mount /opt/vm/rtems
u2004:/opt/vm/rtems"
3) upgrade expat to 2.4.8 and gmp to 6.2.1
4) before building, specify "ulimit -n 4096" on the linux VM otherwise
GCC will fail to link with incomprehensible error.
