uClibc pretends to be glibc 2.2. But currently it doesn't use
PT_GNU_EH_FRAME segment. So we cannot define USE_PT_GNU_EH_FRAME and
have to register and deregister frame info.
Is it OK to commit?

This is wrong, it should never be pretending to be glibc. This is
just as bad as ICC pretending to be GCC.

Probably true, but irrelevant to Jie's patch.
