It does not surprise me that this happens.  I spent quite a bit of 
effort getting --gc-sections working on mipsel-linux, but I never tried 
it in conjunction with --export-dynamic.

Unfortunately I don't know of any alternative to running ld under a 
debugger and figuring out what is going wrong, and then fixing it.
