We need only libbfd, libiberty and libopcodes from binutils native.
To get them we build entire binutils with --enable-targets=all to
include all possible output targets support and then remove all but
these three libs.
This has two side effects:
1) it wastes build time
2) may cause errors caused by --enable-targets=all on some exotics
build hosts like PowerPC 32bit
To address both of these effects we can configure binutils in general
and only required libs and their dependencies (zlib and intl at the
time). Then build only build these libs and their dependencies.
Regarding to PowerPC 32-bit build host issues we get following errors
when building on Ubuntu 16.04 LTS for PowerPC with command:
MACHINE=qemuppc setarch ppc bitbake binutils-native

<output omitted>
While 'byte_get' is defined in small bss section in elfcomm.o and
generally can be fixed, symbol from host glibc 'stdout@@GLIBC_2.0' in
small data section can't be moved without recompile of Ubuntu 16.04 LTS
glibc.
