I have vague memories of a flag in the makefile that allowed
the ecw support to be built separately. The drill was something like
1) build gdal without ecw support (so that it's not statically linked)
2) go into the ecw format directory and build there independently,
    after tweaking the makefile or somethign like that
3) place the resulting library in a special directory

Cheers
