Hello,

This commit may need to be reversed, and here is my explanation:

The p5-DBD-mysql package doesn't actually use pthread.  It depends on
mysql*-client, and uses "mysql_config --libs" to determine what
libraries to link,  This is where the -lpthread comes from.  But if you
look at the mysqlclient library itself, you'll see that it doesn't link
to libpthread.

sanctum $ ldd /usr/pkg/lib/mysql/libmysqlclient.so | grep thread
sanctum $ ldd /usr/pkg/lib/mysql/libmysqlclient_r.so | grep thread
         -lpthread.20 => /usr/pkg/lib/libpthread.so.20

The correct fix is to either add .include "../../mk/pthread.buildlink3.mk"
to mysql*-client/buildlink3.mk, or to modify mysql_config to stop
reporting -lpthread.  I suspect the latter, since recently
libmysqlclient was explicitly changed to stop depending on pthread.

see pkg/28162

Cheers,

Ben
