Subject: [PATCH] phpdbg_prompt: enclose phpdbg_load_module_or_extension() in
 HAVE_LIBDL

The phpdbg_load_module_or_extension() function relies on libdl
functionality, so it should be enclosed in HAVE_LIBDL to avoid the
following build failure when libdl support is not available:

php-7.0.9/sapi/phpdbg/phpdbg_prompt.c:(.text+0x1c20): undefined reference to `_DL_LOAD'
php-7.0.9/sapi/phpdbg/phpdbg_prompt.c:(.text+0x1c36): undefined reference to `_GET_DL_ERROR'
php-7.0.9/sapi/phpdbg/phpdbg_prompt.c:(.text+0x1c6a): undefined reference to `_DL_FETCH_SYMBOL'
php-7.0.9/sapi/phpdbg/phpdbg_prompt.c:(.text+0x1c7e): undefined reference to `_DL_FETCH_SYMBOL'
php-7.0.9/sapi/phpdbg/phpdbg_prompt.c:(.text+0x1dc6): undefined reference to `_DL_UNLOAD'

This function is only called in the "dl" debug command, inside an
HAVE_LIBDL condition.
