Actually, on GNU/Linux src/gmalloc.c (which contains the code in
question) is not even compiled, normally.
The reason for your compilation troubles seems to be that you use
a recent git checkout of glibc (as you stated above) which I guess
already contains
http://repo.or.cz/glibc.git/commitdiff/2ba3cfa1607c36613f3b30fb1ae4ec530245ce64
IIUC, this commit removes the declaration of __malloc_initialize_hook,
so the emacs configure check for "whether malloc is Doug Lea style"
will fail.
And this is the reason why you suddenly need malloc etc. from
src/gmalloc.c.
