Subject: [PATCH] gcc: xtensa: don't force PIC for uclinux target
xtensa-uclinux uses bFLT executable file format that cannot relocate
fields representing offsets from data to code. C++ objects built as PIC
use offsets to encode FDE structures. As a result C++ exception handling
doesn't work correctly on xtensa-uclinux. Don't use PIC by default on
xtensa-uclinux.

[PATCH] cilk: fix build without wchar
When building against uClibc with wchar support disabled, WCHAR_MIN and
WCHAR_MAX are not defined leading to compilation errors.
Fix it by only including the wchar code if available.

Subject: [PATCH] Make MicroBlaze support DWARF EH (old Xilinx patch, needed
for glibc build).
This patch, taken from
<https://git.busybox.net/buildroot/tree/package/gcc/5.4.0/840-microblaze-enable-dwarf-eh-support.patch>
and with a few formatting cleanups and an update for the removal of
gen_rtx_raw_REG, enables DWARF EH support for MicroBlaze.
This is needed for building glibc with a compiler that includes shared
libgcc; right now all glibc builds for MicroBlaze are failing with my
bot for lack of this support. (It's dubious if we should have glibc
ports at all where required support is missing in FSF GCC.)
Tested building glibc with build-many-glibcs.py. I have *not* done
any other testing or any execution testing for MicroBlaze.
