>     Fix debugging of stripped PIE executables with padded PT_TLS
>     
>     Certain PIE executables produced by gold cannot be debugged by gdb after
>     being stripped. GDB requires program headers of PIE executables to match,
>     and those checks may fail due to adjustments made during stripping.
>     
>     One case of this occurs because strip recomputes the memsz of PT_TLS and
>     does not add alignment, while gold does. This is another variant of PR
>     11786, so apply the same fix of relaxing the program header matching.

>     gdb/ChangeLog:
>     
>     	PR gdb/11786
>     	* solib-svr4.c (svr4_exec_displacement): Ignore memsz fields
>     	for PT_TLS segments.

>     gdb/testsuite/ChangeLog:
