[MXE Octave] build transfig on Debian wheezy, ac_cv_func_malloc_0_nonnull=yes

[Andreas Weber]

If I try to build Octave on Debian 7.8 wheezy it fails on transfig with
"undefined reference to `rpl_malloc'"

I had to patch transfig.mk to built it:

diff -r 078b47125239 src/transfig.mk

 define $(PKG)_BUILD
+    cd '$(1)' && export ac_cv_func_malloc_0_nonnull=yes
     cd '$(1)' && chmod 755 configure && aclocal && automake
--add-missing && autoconf \
         && $($(PKG)_CONFIGURE_ENV) '$(1)/configure' \
         BITMAPDIR="/share/$(PKG)/bitmaps" \

But verly likely there is a better way to fix this.
