Description:
------------
#46964 introduced a new bug. The patch there to fix compilation issues actually breaks the feature.

ext/pdo_mysql/mysql_driver.c has this line:
#if defined(MYSQL_OPT_LOCAL_INFILE) || defined(PDO_USE_MYSQLND)

MYSQL_OPT_LOCAL_INFILE is not a macro. It's an enum.
The defined() will always be false and the block will not be compiled.

One way to fix this is to add a configure check which compiles a program like this:
#include <mysql/mysql.h>
int opt = MYSQL_OPT_LOCAL_INFILE;

When it cannot be compiled, the enum isn't defined. Then define some macro or so which can be checked by the preprocessor.

Work around for the problem:
* add to options array: PDO::MYSQL_ATTR_READ_DEFAULT_GROUP => 'client'
* add to /etc/mysql/my.cnf:
[client]
local-infile = 1

That[1].

This issue has been resolved for mysqlnd by fixing bug #54158, but
still persists for libmysql-client.
