Thumbs up.

I would phrase it a little differently:

- you changed the default location of objcopy when cross compiling
   is enabled which potentially enables FDS for cross compiling
- if ALT_OBJCOPY is set, then that value is used (even if it does
   not refer to an executable program)

Setting ALT_OBJCOPY to some non-existent value is the means by which
FDS can be completely disabled for all build configs on both Linux and
Solaris. Note: there isn't a means to disable FDS on all build configs
on Windows.
