 Attempting to build the ARM/4.12 BSet using RSB on Fedora 23 X86_64.  The
 RSB repository clone was up to date (22/01/2016).  I had previously built
 the same BSet from the repository up to date as of 09/01/2016.  When
 building newlib, I got the following:

 Sebastian commented that the binutils being used was out of date and I
 noticed that it was picking up the binutils from my previous build.  I
 removed the previous build from my PATH, but got the same issue.  I
 examined the logs and discovered that RSB was adding the installation bin
 directory to the PATH while executing.  I renamed the original $PREFIX so
 that it was no longer building into an existing directory and the build
 ran successfully.

 It appears that RSB will not build newlib successfully if it is installing
 into the same location as a previous build that does not contain
 compatible tools.
