commit 44b456205a0cb823fc61dc0f5a3f7c4ff19c8921
Author: Florian Weimer <fweimer@redhat.com>
Date:   Sat Feb 8 09:15:05 2020 +0100

    ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]
    
    Exporting functions and relying on symbol interposition from libc.so
    makes the choice of implementation dependent on DT_NEEDED order, which
    is not what some compiler drivers expect.
    
    This commit replaces one magic mechanism (symbol interposition) with
    another one (preprocessor-/compiler-based redirection).  This makes
    the hand-over from the minimal malloc to the full malloc more
    explicit.
    
    Removing the ABI symbols is backwards-compatible because libc.so is
    always in scope, and the dynamic loader will find the malloc-related
    symbols there since commit f0b2132b35248c1f4a80f62a2c38cddcc802aa8c
    ("ld.so: Support moving versioned symbols between sonames
    [BZ #24741]").
    
    Tested on i686-linux-gnu with out the stack protector, and on
    x86_64-linux-gnu with stack-protector-strong.  Also built with
    build-many-glbics.py.
