[PATCH v3 0/1] aarch64: Add ifuncs for malloc functions

[Yury Khrustalev]

See commit message for details. In a nutshell, we want to add ifuncs
for the functions related to the malloc API (on targets that support
ifuncs). This will allow to add alternative (e.g. target-specific)
implementations or wrappers for these functions.

This patch introduces ifuncs for malloc functions for aarch64 in
multiarch mode.

Changes in v3:
 - Moved all ifunc code into multiarch folder under aarch64, so this
   change is now aarch64-only not affecting other targets.
 - v2: https://inbox.sourceware.org/libc-alpha/20260420141459.531612-1-yury.khrustalev@arm.com

Changes in v2:
 - Fixed ifunc resolvers arguments: use no arguments for generic resolvers
   and use 'uint64_t arg0, uint64_t arg1[]' for aarch64 resolvers.
 - Added grep test to check that code in malloc.c doesn't use non-_core
   functions.
 - Cleaned-up makefile patch.
