xtensa: disable link optimization
The default linker behavior is to optimize identical literal values and remove unnecessary overhead. However, because of a bug in the linker, this currently results in an error ('call target out of range'). Disable link-time optimizations per default until there is a fix for the linker and add the option to iss_defconfig. Signed-off-by: Chris Zankel <chris@zankel.net>
