[meta-oe][PATCH 2/2] libdbd-mysql-perl: fix do_compile failure

[<mingli.yu@windriver.com>]

From: Mingli Yu <mingli.yu@windriver.com>

After mariadb upgrade to 10.3.13, there comes
below do_compile failure for libdbd-mysql-perl:
| dbdimp.c: In function 'mysql_dr_connect':
| dbdimp.c:2000:13: error: 'MYSQL' {aka 'struct st_mysql'} has no member named 'reconnect'
|        result->reconnect=0;

Backport a patch to fix it.

+Subject: [PATCH] Use API function for reconnect
+
+For configuring reconnect functionality use standard API function
+MYSQL_OPT_RECONNECT instead of direct modification of internal structures
+which does not work for MariaDB. Fixes compilation with MariaDB 10.2.6+.
+
+Upstream-Status: Backport [https://github.com/perl5-dbi/DBD-mysql/commit/0b1884f4153d3de0a91bae4d3b3cc1771ffdf4f3]
