Add a test for debuginfo generation

Add a check to ensure debug info generation works.

We piggyback on a test that already builds DWARF symbols (--debug)
The test
1) makes the debuginfo files
2) runs gdb, loading the libcrypto.so.3 file
3) Check to make sure that the output of gdb indicates that it loads the
   .debug file base on the reference in the loaded file
