   4 Subject: [PATCH] Drop AC_FUNC_MALLOC and _REALLOC and check for them as
   5  regular functions.
   6
   7 While cross-compiling there occurred "undefined reference to
   8 `rpl_malloc'", the suggested change fixes the problem.

  10 Tested for native X86_64 and armv7a-unknown-linux-gnueabihf.
