Description:
------------
When compiling an extension with phpize, it is not linking to the libphp5_common.so.5.3.0. Had to create a new link and add PHP_ADD_LIBRARY(php5_common, 1, TEXAS_API_SHARED_LIBADD).

This has wasted hours.

Test script:
---------------
1) create test extension:- ./ext_skel --extname=test
2) mode config.m4 to enable:- PHP_ARG_WITH(test, for Texas API support,[  --with-test        Include Test support])
3) run phpize in module directory
4) run ./configure --with-test
5) run make
6) ld modules/test.so

Expected result:
----------------
ld: warning: cannot find entry symbol _start; not setting start address
/usr/lib64/../lib64/libphp5_common.so.5: undefined reference to `php_register_internal_extensions'


Actual result:
--------------
ld: warning: cannot find entry symbol _start; not setting start address
