MySQL Connector Extension Build on Linux 32bit

As some of you will probably know by now due, I attempt to provide the 
mysql native connector extension for Linux 32 bit, 64 bit and OSX 64bit.

At present, the 32bit Linux build doesn't work on other people's 
machines with a similar base OS, whereas the Linux 64bit does. There is 
a noticeable difference in size between the two OXT files, and 
comparison of the two shows the following :

What I'm failing to understand is why this is happening. The basic build 
systems are based on Ubuntu 13.04 Raring, and use exactly the same build 
switches, the only difference being that the 64bit OS is Linux Mint 15 
Olivia (based on Ubuntu 13.04), and the 32bit is a default Ubuntu 13.04 
Raring. Something is obviously failing to be included during the 32bit 
build, but what ?

64bit :
  5113839  2013-10-11 15:06   libmysqlcppconn.so
  3802154  2013-10-11 16:35   mysqlc.uno.so

32bit :
   667046  2013-10-14 14:15   libmysqlcppconn.so
   484084  2013-10-14 14:29   mysqlc.uno.so


Any help much appreciated.
