It looks like the arm cross compiler doesn't support --sysroot:

$ mkdir -p mysysroot/usr/include
$ echo > mysysroot/usr/include/test.h
$ echo "#include <test.h>" > test.cpp

$ arm-linux-gnueabi-cpp-4.6 --sysroot=$PWD/mysysroot test.cpp
# 1 "test.cpp"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.cpp"
test.cpp:1:18: fatal error: test.h: No such file or directory
compilation terminated.

Where as the regular cpp works:

cpp --sysroot=$PWD/mysysroot test.cpp

# 1 "test.cpp"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.cpp"
# 1 "/home/foobar/test/mysysroot/usr/include/test.h" 1 3 4
# 1 "test.cpp" 2
