Given the fact that that GNU tools can be used across platforms is good
reason why lots of tests are ignored or XFAIL.

Also, the fact that devs keep creeping non perl way of doing things like
Bc commands could do, means that we now have to include Bc during tools
and cross-compile it so the final system can pass the tests requiring Bc
as they didn't include the configure options to ignore/skip thoses tests
if Bc is not included with the running system.

It's like the autoconf/automake test suite where Autoconf needs Automake
to complete the testsuite. So you install automake then go back and test
autoconf. Just do that with binutils. Install Bc, then go back and test.
Or just run the relro test by itself.

Simple:

1) Add a note in the book for Binutils to install Bc then come back and test.
2) Install Bc in /tools
