we use an automatically generated user-config.jam to control the gcc version 
and the build flags. This allows us to build 32 bit and 64 bit versions

for 64 bit we set
flag=-m64

for 32 bit we set
flag=-m32

cat >user-config.jam <<@@END@@
# Boost.Build Configuration
# Automatically generated by ${scriptname}

# Compiler configuration
using gcc : : ${GCC_BASEDIR}/g++-${GCCVERSION} : <compileflags>${flag} 
<compileflags>-I${buildprefix}/include <compileflags>-L${buildprefix}/lib 
<linkflags>${flag} <linkflags>-L${buildprefix}/lib ;
