Perhaps, but this has the unwanted side effect of introducing a
different and uncessary code path when cross-compiling.  Even though
autoconf recommends that a replacement be available, it would also be
proper to detect that the target uses an approved GNU C library and
not require the replacement malloc.

There has been some talk about using cross-compilation to increase the
throughput and flexibility of the build systems.  This macro will
cause native and cross-compiled binaries to be different which will
make it harder to prove that the programs are identical.  If the
programs are not obviously the same, there will be good reason to
doubt that cross-compilation is reliable.
