Not sure - that seems to be a bug in the hotspot build (hence cc 
hotspot-dev). The FDS logic is processed multiple times but the initial 
pass should disable FDS for the subsequent uses. If gobjcopy is 
installed somewhere then ALT_OBJCOPY can be set to point to it. Was this 
part of a full build? The configure process might also find gobjcopy and 
set the appropriate variables.
