Actually: the wrong bfd.h because -I/usr/local/include is too early
and overrides the local -I usage and binutils is installed:

# find / -name bfd.h -print | less
/usr/local/include/bfd.h
/usr/src/gnu/usr.bin/binutils/libbfd/bfd.h
/root/c_tests/ppc64_tls_git/bfd/bfd.h

# pkg which /usr/local/include/bfd.h
/usr/local/include/bfd.h was installed by package binutils-2.30_6,1

The 2 files do not seem to be equivalent.
