[Qgis-user] building gdal for mrsid

[Don Harter]

I finally got this to build.  It was at least a problem at my end.  I 
had several versions of compilers and cross compilers installed.  
Somehow they were getting mixed up with the linkers.  I reinstalled all 
my gcc compilers and got a successful build.  I had changed all the 
compile options to -no-lto from -flto etc.  I need to clean that up and 
add some more meaningful options for checkinstall.
