Add debug output for recorded minsyms
While discussing this issue:
https://sourceware.org/ml/gdb-patches/2018-12/threads.html#00082
I added a printf gated by "set debug symtab-create" to be able to
quickly see all minimal symbols recorded by GDB. I thought it would be
useful to have it built-in, for the future. Here's how the output
looks:
Recording minsym: mst_data 0x400780 15 _IO_stdin_used
Recording minsym: mst_text 0x400700 13 __libc_csu_init
Recording minsym: mst_bss 0x601058 25 _end
gdb/ChangeLog:
* minsyms.c (mst_str): New.
(minimal_symbol_reader::record_full): Add debug output.
