RTEMS 4.12 gcc-7.1.0/binutils-2.28 test results

[Chris Johns]

Hi,

I am testing RSB patches to move 4.12 to gcc 7.1.0/binutils-2.28.

The SH arch fails to build on FreeBSD 11.0. The issue is
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80923.

The SH failures are expected because there are no tools. I have reached out to
find a solution here.

The PowerPC failures are due to using binutils-2.28 and linking the bootloader.
It is broken. The linker is generating lots of messages like:

/opt/work/chris/rtems/kernel/rtems.git/c/src/lib/libbsp/powerpc/motorola_powerpc/bootloader/../../../powerpc/shared/bootloader/head.S:140:(.text+0x8a):
dangerous relocation: generic linker can't handle R_PPC_SECTOFF_HA

This bug exposes a PowerPC BSP build system error where running make again does
not generate the error. It seems the RALF file rules are broken.

I am happy to push the patches to update to gcc-7.1.0 and binutils-2.28 and keep
SH on the current tools and the PowerPC on binutils-2.27.

I will run a build of everything with tests.
