This patch looks very very confused to me. Firstly your subject summary
talks about libgcc-nativesdk. This is the compiler used to generate
binaries for SDKMACHINE so I seriously doubt you're using nativesdk to
build uboot.

This is changing the packging of libgcc too, not just libgcc-nativesdk.
It is not correct to be putting the dynamic linking symlinks in anything
but the -dev package so the above and the line below are therefore wrong
too.

Equally, you're moving a static library from the -dev package into the
main package which is wrong, you only need that if you're doing
development.

Are you sure your problem is not that you didn't have the libgcc-dev
package installed?
