This is probably not specifically an EPICS issue, it looks more likely that 
you have some incompatibility between your cross-build environment for C++ and 
the SBC linux installation you're trying to use.

Some clues to look for:  Does the SBC actually have a copy of libstdc++.so.5?  
Is it the same as the one that your cross-gcc linked the vlinac against?  If 
you run ldd on the linac binary (on the ARM system), does it show that as a 
missing library?

You might need to build EPICS Base and the IOC as purely static binaries with 
no shared libraries, which you would do by creating a file in base called 
configure/os/CONFIG_SITE.Common.linux-arm file which contains the lines
    STATIC_BUILD=YES
    SHARED_LIBRARIES=NO
Then you have to rebuild base by typing 'make rebuild' in the top directory of 
your base installation, and rebuild the vlinac application similarly.

HTH,
