elf: Initialize GLRO(dl_lazy) before relocating libc in dynamic startup
|
||
|
|
|
||
|
|
GLRO(dl_lazy) is used to set the parameters for the early
|
||
|
|
_dl_relocate_object call, so the consider_profiling setting has to
|
||
|
|
be applied before the call.
|
||
|
|
|
||
|
|
Fixes commit 78ca44da0160a0b442f0ca1f253e3360f044b2ec ("elf: Relocate
|
||
|
|
libc.so early during startup and dlmopen (bug 31083)").
