# SHELL wrapper that intercepts config.sub calls and uses our updated version
|
||
|
|
# This allows building with autoconf projects without modifying their config.sub files
|
||
|
|
#
|
||
|
|
# How it works:
|
||
|
|
# - autoconf's configure runs: $SHELL "${ac_aux_dir}config.sub" $host_alias
|
||
|
|
# - By exporting SHELL to point to this script, we intercept these calls
|
||
|
|
# - When $1 ends with "config.sub", we use our version instead
|
||
|
|
# - All other invocations pass through to real bash
|
||
