Comment (by Chris Johns):

 To debug this run the command with the options `--trace` and `--dry-run`
 as this is an RSB config issue. Running:
 {{{
 ../source-builder/sb-set-builder --prefix=/opt/work/rtems/6 --log=a.txt
 --trace --dry-run 6/rtems-aarch64
 }}}
 shows in the log:
 {{{

 The issue is the python config command outputting more than one library
 and the `awk` post processing turning this into more than one line:
 {{{
  /usr/bin/python3-config --ldflags --embed
 -L/usr/lib/python3.9/config-3.9-x86_64-linux-gnu -L/usr/lib/x86_64-linux-
 gnu -lpython3.9 -lcrypt -ldl  -lm -lm
 }}}
 The breaks the library check script.
