After applying this patch, I get another build failure building
gcc-4.2:

dh_builddeb -plibstdc++6

build/arm-linux-gnu/libstdc++-v3/testsuite contains:
baseline_dir = /home/tbm/build/42/3/gcc-4.2-4.2-20070516/src/libstdc++-v3/config/abi/post/$(MULTISUBDIR)

The sed will give you:

sed -n '/^baseline_dir *=/s,.*= *\(.*\)\$.*$,\1,p' Makefile
/home/tbm/build/42/3/gcc-4.2-4.2-20070516/src/libstdc++-v3/config/abi/post/

(MULTISUBDIR seems to be empty, btw)

Any idea what to do about this?  Giving that there's no "arm" directory, I
suppose simply replacing mkdir with mkdir -p would work.
