FS#979 - Remove autoconf test for malloc

----------
AC_FUNC_MALLOC actually checks whether malloc(0) returns a valid pointer (compatible with gnu malloc). http://www.mail-archive.com/autoconf@gnu.org/msg08931.html
I would hope that we do try to malloc 0 bytes. In this case removal would be save.

If we want to be able to use malloc(0), we need to provide a fallback version allowing malloc(0).

Therefore the question is:
Do we think malloc(0) is allowed or do we accept undefined behaviour for this call?

If we opt for the first we should probably also consider realloc(0) etc.
