Status of 4.12 and Tool Masters

[Joel Sherrill]

Hi

I did a sweep to build all tools and targets using the master
on a Centos 7 host. The big change was a feature flag rework
in newlib and Sebastian fixed the compile issues before I started.
Here is what I have noted:

+ newlib - guard for ftello/fseeko is not right. Being fixed.
+ newlib - epiphany defines its own srand() method. We don't
   have this method on any other target so don't use this.
+ binutils - epiphany doesn't seem to be supported by as/ld
+ gcc - RTEMS epiphany patch is missing
+ m32c - gcc Internal Compiler Error compiling newlib
+ moxie - requires dtc to build gdb. Does sb-check look for this?
   Not sure where  to install this from on Centos 7. Need to use
   RTEMS RSB for this before building Moxie. Can this be addressed
   in the RSB?
+ or1k GCC - GCC is not upstream

The moxie is something we might be able to improve. The epiphany
needs pushing.  I asked on newlib if m32c-elf did the same on the
test sweep of the feature flags. If not, I will file a GCC ticket.
