ld.so: Remove __libc_memalign
It is no longer needed since commit 6c444ad6e9
(elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]).
Applications do not link against ld.so and will use the definition in
libc.so, so there is no ABI impact.

|

|
||||
Remove __libc_memalign from ld.so because it is unused.
|
||||
* elf/dl-minimal.c: Update comment on the malloc implementation.
|
||||
(malloc): Renamed from __libc_memalign, replacing the original
|
||||
malloc implementation. Replace the align parameter with
|
||||
MALLOC_ALIGNMENT.
