Can you add export LDFLAGS=-verbose to your mozconfig, then run the following commands:

./mach configure
./mach build -v -C . pre-export export mozglue/build/target

Then please attach the full output of those commands.

Sorry for the delayed response, I updated my toolchain and the issue is no more!
