You have an out-of-range branch. Branches can only reach about 16MB directly,
after that they need linker help.
If you have a recent enough toolchain, then -Wl,-relax will make this work.
It should work automatically, but well, eventually it will. The recent
TurboLinux distribution RPMS have the necessary patches. I don't believe any
Red Hat distribution RPMS have it yet, but the next release will.
A 32-bit hosted cross compiler will generate worse code than a native compiler.
This is because it is harder to optimize 64-bit values on a 32-bit machine, so
there are some cases where we just give up and don't perform the optimization
when on a 32-bit host. Thus the cross compiled application will be bigger,
and more likely to have out-of-range branches. Don't cross compile unless
you have to.
Jim
