Extensions no longer registered in master Linux 32bit

[Alex Thurgood]

Hi,

For some reason, extensions no longer appear to be registered as 
components since the switch to instdir.

If I open Tools > Extensions, the Extension Manager shows an empty window.

Running unopkg.bin from instdir also indicates that no extensions are 
registered.

However, I see them in
solver/unxlngi6.pro/bin/

and also some of them in
workdir/unxlngi6.pro/Extension
