Even if you have no debug info, you should still be able to put a breakpoint
on functions.  GDB knows the functions exist from the ELF symbol tables (minsyms):

 Reading symbols from testsuite/outputs/gdb.base/break-interp/break-interp-BINprelinkNOdebugNOpieNO...
 (No debugging symbols found in testsuite/outputs/gdb.base/break-interp/break-interp-BINprelinkNOdebugNOpieNO)
 (gdb) b main
 Breakpoint 1 at 0x40074b
 (gdb) 

Thanks,
