[build] Check for broken elftoolchain version of objcopy
The elftoolchain version of objcopy (as used in FreeBSD) seems to be
unusable for generating a raw binary file, since it will apparently
ignore the load memory addresses specified for each section in the
input file.
The binutils version of objcopy may be used on FreeBSD by specifying
OBJCOPY=/usr/local/bin/objcopy
Detect an attempt to use the unusable elftoolchain version of objcopy
and report it as an error.
