> 
> This patch fixes an issue that occurs during the manual build process
> which will occur when BR2_EXTERNAL is introduced.
> 
> During the package list generation, the python script using kconfiglib
> module reads and parses the Config.in files. So, symbols, including
> environment variables, got expanded and/or resolved.  In
> kconfiglib.py, this patch fixes the regex that did not allow to use
> numbers in the environment variable names, so '$BR2_EXTERNAL' got
> wrongly expanded like it was '${BR}2_EXTERNAL':
