This issue is because:
Your system gdb's debug-file-directory is set to "/usr/lib/debug".
(gdb) show debug-file-directory 
The directory where separate debug symbols are searched for is "/usr/lib/debug".
Then this gdb work with debug lib is OK.

The debug-file-directory of gdb that compiled by yourself is set to
"/usr/local/lib/debug".
(gdb) show debug-file-directory
The directory where separate debug symbols are searched for is
"/usr/local/lib/debug".
Then this gdb can't find the debug lib.
you can set it with your self.
For example:
(gdb) set debug-file-directory /usr/lib/debug
(gdb) attach 21190

And the debug-file-directory is set in gdb configure, so you can change it by
re-config your gdb.
