Since GCC 3.4 is the first release to support shared libs for FR-V, the symbols exported by libgcc are marked as GCC_3.4. Since glibc brings them into libc.so, we have to export them. It might be worth noting that the FR-V ABI specifies different names for the functions traditionally exported by libgcc, and GCC actually emits references to these alternate names, that are thus brought into libc.so from libgcc.a. I couldn't find any way to introduce this as part of the ports infrastructure, unfortunately.
