Before this change _invalid_pc_placeholder pointed to address of _init
function from crti.o
This made GDB input a bit confusing:
0x40080400 in _init ()
(gdb) bt
#0 0x40080400 in _init ()
#1 0x400e519a in test_instr_fetch_prohibited () at /home/alex/git/esp-idf/tools/test_apps/system/panic/main/test_panic.c:271
#2 0x400d89a7 in app_main () at /home/alex/git/esp-idf/tools/test_apps/system/panic/main/test_app_main.c:116

After the change GDB prints output that contains a hint:
_invalid_pc_placeholder () at /home/alex/git/esp-idf/components/xtensa/xtensa_vectors.S:2235
2235 UNREACHABLE_INSTRUCTION_CHECK_PREVIOUS_FRAMES

This feature is useful for 3rd-party software to run GDB with predefined
options that described in project_description.json file
allow to pass custom options to "idf.py gdb":
--gdb-commands: command line arguments for gdb. (without changes)
-ex: pass command to gdb.
-x: pass gdbinit file to gdb. Alias for old --gdbinit command
The default newlib read/write syscalls automatically convert newline
endings from LF to CRLF on stdout. Therefore, the test should not
specifically check for LF in the expected output, as the standard
conversion for stdout is CRLF. While it is possible to change the
expected line ending in the test from LF to CRLF, it seems more
dependable to just avoid verifying line endings entirely.

Test app to ensure that bootloader and application built with
different flash MMU page size are compatible. This is for the
SoCs that support configurable flash MMU page size.
ram_app: support c5 c61, fixed PMA15 occupied by ROM issue
Closes IDF-8644, IDF-9251, IDF-10315, and IDF-10951
See merge request espressif/esp-idf!33381
fix(esp_hw_support): make the NMI interrupts available for the main application
Closes IDF-1891 and IDFGH-12631
See merge request espressif/esp-idf!32767
fix(freertos): Added freertos and ringbuf fragments to the exception list of ldgen mapping checks
Closes IDF-10489
See merge request espressif/esp-idf!32702
Closes https://github.com/espressif/esp-idf/issues/13629
NMI interrupt level has been freed for all the Xtensa targets, making it possible
for the main application to use it. An example has been added to show how to
proceed.
