Hi,

When I ran Asan tests under Asan-bootstrapped GCC 5.0, I've noted, that 
tests for libiberty and libbacktrace fail to link with sanitized 
libbacktrace.a and libiberty.a because of missing -static-libasan 
-fsanitize=address linker flags.

This patch adds necessary flags to provide a linkage of these tests in 
bootstrap-asan case.

I've checked that regression tests pass with disabled bootstrap, normal 
bootstrap (stage1, stage3) and Asan-bootstrap (stage 1, stage3) on 
x86_64-unknown-linux-gnu.

Does the patch look sane?

-Maxim

I don't think anything in the toplevel configury looks "sane" any
more, but I think this patch is OK.

Hi DJ, thanks for review.

 > I don't think anything in the toplevel configury looks "sane" any

I'm sorry, I didn't understand this clearly. Does this mean that I 
should wait until Stage 1 starts and commit then, or it is OK now?

I can't say if this fixes a bug important enough for stage4, but if
someone wants to claim that, you won't have to wait for stage 1 :-)
