bug#22464: compilation fails on AIX-7 (undefined symbol .rpl_malloc)

[Assaf Gordon]

Hello,

I just got access to an AIX machine,
compiling 8.25 on AIX-7 fails with "undefined symbol .rpl_malloc".

I'll be able to investigate further a bit later, but this seems similar to:
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=12841
