From 2cc80dc06ea42087788cf27b31821ffa99a22f89 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Drop AC_FUNC_MALLOC and _REALLOC and check for them as
regular functions.
While cross-compiling there occurred "undefined reference to
`rpl_malloc'", the suggested change fixes the problem.
Tested for native X86_64 and armv7a-unknown-linux-gnueabihf.
