[PD] flext externals crash PD

[Thomas Grill]

Hi Jacob,
many thanks for your findings... the -Wl,-x strips local symbols from 
the binary... i'm wondering though why it crashes for you but not for 
me.....
Can you give me some details about your configuration (OS/gcc/PD 
versions etc.)?
In any case i removed the switch in the flext cvs version.

best greetings,
Thomas
