That's expected - in general you can't build a native compiler on one system and expect it to work on a different system. Unless you built a cross-compiler, the compiler built on RHEL expects to find the same version of glibc on the host system where it runs. The version on the SuSE machine is different. You should build GCC on the SuSE machine for use on the SuSE machine, or build a "Canadian Cross" compiler on RHEL.
