non-gcc: Remove trailing whitespace

I've tried to build stage3 with
-Wleading-whitespace=blanks -Wtrailing-whitespace=blank -Wno-error=leading-whitespace=blanks -Wno-error=trailing-whitespace=blank
added to STRICT_WARN and that expectably resulted in about
2744 unique trailing whitespace warnings and 124837 leading whitespace
warnings when excluding *.md files (which obviously is in big part a
generator issue).  Others from that are generator related, I think those
need to be solved later.

The following patch just fixes up the easy case (trailing whitespace),
which could be easily automated:
for i in `find . -name \*.h -o -name \*.cc -o -name \*.c | xargs grep -l '[ 	]$' | grep -v testsuite/`; do sed -i -e 's/[ 	]*$//' $i; done
I've excluded files which I knew are obviously generated or go FE.

Is there anything else we'd want to avoid the changes?

Due to patch size, I've split it between gcc/ part
and rest (include/, libiberty/, libgcc/, libcpp/, libstdc++-v3/;
this part).
