pkg_add gdb and use the 'egdb' command.

gmake compile of python3.12 crashes on openBSD 7.5 but not on openBSD 7.4

[Sandeep Gupta]

I was able to compile Python 3.12 from source code on openBSD 7.4. However,
after upgrade to 7.5 the compile process crashes with core dump:

cc -pthread   -g  -Wl,--export-dynamic -o Programs/_testembed
Programs/_testembed.o -L. -lpython3.12 -lpthread  -lutil
 -lm
_testembed.c:1848
(./Programs/_testembed.c:1848)(Programs/_testembed.o:(test_init_use_frozen_modules)):

  I am unable to find a proper debugger into which to load the python.core
generated after core dump, so can't provide any useful debug info.
I don't think this is due to some changes in Python code that is creating
the core dump. Any ideas would be helpful.
