ld.so: Remove __libc_memalign

Browse Source 
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.

# The dynamic loader uses __libc_memalign internally to allocate aligned
# TLS storage. The other malloc family of functions are expected to allow
# user symbol interposition.
# It is also allowed to call __libc_memalign via function-pointer loaded from
# GOT instead of calling via a plt-stub. In this case there is a R_390_GLOB_DAT
# relocation in section .rela.dyn instead of R_390_JMP_SLOT in .rela.plt.
# After commit "elf: Do not use memalign for TCB/TLS blocks allocation
# [BZ #17730]" __libc_memalign is only called in elf/dl-minimal.c: malloc() in
# ld.so and gcc -O2/-O3 leads to R_390_GLOB_DAT. If build with
# -fno-optimize-sibling-calls an R_390_JMP_SLOT is generated.

# The main malloc is interposed into the dynamic linker, for
# allocations after the initial link (when dlopen is used).
