--- Comment #2 from Petr Ovtchenkov <abominable-snowman at yandex dot ru> ---
No, adding

--with-sysroot=/export/staging/ptr/continuous/development/../arm-unknown-linux-gnueabi
\
       
--oldincludedir=/export/staging/ptr/continuous/development/../arm-unknown-linux-gnueabi/usr/include 

don't change situation at all:

...

libtool: compile: 
/export/staging/ptr/continuous/development/../toolchain-arm-continuous-linux-gnueabi/bin/arm-continuous-linux-gnueabi-c++
-I/export/staging/ptr/continuous/development/build-gcc/arm-unknown-linux-gnueabi/libstdc++-v3/include/arm-unknown-linux-gnueabi
-I/export/staging/ptr/continuous/development/build-gcc/arm-unknown-linux-gnueabi/libstdc++-v3/include
-I/export/staging/ptr/continuous/development/gcc/libstdc++-v3/libsupc++
-I/usr/include -std=gnu++98 -fPIC -DPIC -fno-implicit-templates -Wall -Wextra
-Wwrite-strings -Wcast-qual -Wabi -fdiagnostics-show-location=once
-ffunction-sections -fdata-sections -frandom-seed=compatibility.lo -g -O2
-D_GNU_SOURCE -c ../../../../gcc/libstdc++-v3/src/c++98/compatibility.cc  -fPIC
-DPIC -D_GLIBCXX_SHARED -o .libs/compatibility.o
...

The -I/usr/include still here.

BTW, --with-sysroot not required, due to DESTDIR=${SYSROOT}.
