Bug#633739: clang is not fully multiarch

[Jean-Louis Dupond]

Package: clang
Version: 2.9-7
Severity: normal

Some package ftbfs in Ubuntu because clang can't find headers in 
multiarch dirs.

For example:
make[3]: Entering directory `/build/buildd/libdispatch-0~svn197/src'
/bin/bash ../libtool  --tag=CC   --mode=compile clang -DHAVE_CONFIG_H 
-I. -I../config -I.. -I..    -Wall  -fblocks -I/usr/include/kqueue   -g 
-O2 -c -o libdispatch_la-apply.lo `test -f 'apply.c' || echo './'`apply.c
libtool: compile:  clang -DHAVE_CONFIG_H -I. -I../config -I.. -I.. -Wall 
-fblocks -I/usr/include/kqueue -g -O2 -c apply.c  -fPIC -DPIC -o 
.libs/libdispatch_la-apply.o

Would it be possible to make clang completely multiarch?
Cause now i386 dirs doesn't get included.


Thx
