Display relative paths instead of absolute paths in backtrace output, making the output cleaner and more portable across different build environments. This works by adding a SRCTREE define to lib/backtrace.c and stripping it from filenames when printing. Series-to: concept Series-cc: heinrich Cover-letter: backtrace: Add runtime support for looking at the backtrace In some cases the backtrace contains useful information, such as whether a particular function was called earlier in the stack. This series provides a very simple backtrace library, along with some sandbox-specific functions to allow it to work. It is designed such that another arch could implement it. A new 'backtrace' command provides access to the backtrace. END Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
