[linux]invalid conversion from 'void*' to 'HB_PositionRec_*'

I get some errors while compilling Qt_ARM:

../3rdparty/harfbuzz/src/harfbuzz-buffer.c: In function 'HB_Error hb_buffer_ensure(HB_BufferRec_*, HB_UInt)':

../3rdparty/harfbuzz/src/harfbuzz-buffer.c:77: error: invalid conversion from 'void*' to 'HB_PositionRec_*'

make[1]: *** [.obj/release-shared-emb-arm/harfbuzz-buffer.o] Error 1
make[1]: Leaving directory `/usr/local/Qt_ARM/src/corelib'
make: *** [sub-corelib-make_default-ordered] Error 2

In fact, this is because of compiler g++ cann't convert pointer while compiling a C program. I found there's an error in Makefile of 'src/corelib':
CC            = /opt/crosstool/gcc-4.4.3/bin/arm-linux-g++
CXX           = /opt/crosstool/gcc-4.4.3/bin/arm-linux-g++

So change the CC to correct value.
CC            = /opt/crosstool/gcc-4.4.3/bin/arm-linux-gcc
CXX           = /opt/crosstool/gcc-4.4.3/bin/arm-linux-g++

It works!
