testzebra: pragma weak: detect systems with weak alias and provide alternative
LLVM clang does not support #pragma weak (bug 3679) on OS X. There are other systems where the #pragma weak has varying syntax. Added m4 file from the autoconf archives: http://www.gnu.org/software/autoconf-archive/ax_sys_weak_alias.html Fix up zebra/*_null.c files to use #pragma weak alias or stub functions if not available. It's incomplete in that the different format #pragma enable easier fixes on need. Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang. Tested on linux 64bit.
